Lots of questions lately about sex linked cross breeds. Then a discussion this evening on msn. This is from Rick Kemp's Exhibition Poultrypg 35-36.

1. RIR male x Light Sussex Female
pullets warm buff shade, cockerels white or light yellow. Must be done in this order to work.

2. Brown Leghorn male X Light Sussex female
pullets have light brown head and back with heavy chocolate stripes. Often two small thin stripes of colour run down either side of main stripes. Cockerels are black and white.

3. Buff leghorn male X Light Sussex female
Pullets are buff with occasional slight black markings and cockerels are silvery white also with occasional black markings, but ground markings readily distinguishable.

4. Black Leghorn Male X Barred Rock female
Pullets have pure black head cockerels have white spot on head. Can also use australorp or black langshan male with similar results.

5. Barnevelder Male X Columbian Wyandotte female
Similar results to cross 2.

6. Buff orpington male X Light Sussex female or similar silver female
Buff pullets and yellow/white cockerels

7. Brown leghorn male X barred rock female
cockerels black on top of body with white spot. Beak shanks and toes are yellow. Pullets are all black on top, beak shanks and toes all black or very dark.

8. Golden Legbar male X Light Sussex female
Gold pullets and silver cockerels

9. Golden Legbar male X RIR female
Willow legged pullets and yellow legged cockerels at hatching time

Crosses 8 & 9 have double sex links, also have feathering, with the pullets having fast feathering wings.

10. Golden Legbar male X brown leghorn female
Shank colour—pullets willow and cockerels yellow

11. RIR male X White Wyandotte female
Pullets are brown with a dark stripe running down them, cockerels are silver with black markings.


i hope this helps some folks
:P :lol: :P :lol:
cheers

Barnebars
Male (M): Barnevelder hence Barne....& the
Hen(F)the bar.... can be cuckoo or barred breed with a single comb & dark egg colour.
I always put the male (M) first (out of the darkest brown egg) and female(F) second
example: DoubleLacedBarnevelder(DLB) (male M) x BarredPlymouthRock (BPR) (hen F)

Step 1
DLB x BPR
result = dark barred M (I will call him (M1)) & cull black girls (girls not needed)

Step 2
(M1) x DLB ( unrelated hen )
results =
males: you will get some that look like DLB,
some that have very little lacing,
some nearly black,
some like their dad.
what you are looking for is one that is red with barring and some form of lacing too (M2) cull all others no good.
females: black,
DLB,
redish,
dark barred,
and some that look like DLB with barring(F1) Keep,
in theory these are barnebar hens

Step 3
M2x F1(at this point Fswaped from another group of different blood lines)
results: Male….dark barred DLB(look like dad M2), Light barred DLB barnebar Male
Female….DLB, Barred DLB barnebar hens

Step4
as long as one manages to achieve a bird that is dark red in colour and has the barnevelder lacing with the added barring then they could now be classed as barnebars
Now one must concentrate on type.
One can add more blood at any time by puting a barnebar M over DLB hens,
All Male chicks won’t be pure and need to be culled, although the hen chicks will be pure
( these chick have the advantage of being more barnevelder than their parents)
If for some reason the barnebar M produces normal DLB hens then one has kept the wrong barred M
** The M that is kept should be very washed out in colour, the white in the feather should be wider than the colour part (double and single barred genes??)

At a guess you would follow a similar recipe as for the barnebars given above except using campines and barred rocks.

I'll see if I can find a more detailed recipe for you.

There is a website *link missing*

This information came from http://www.poultrykeepersalmanac.com/br ... eeding.cgi
There are also pics on the website to help.

Cambars - resurrecting an old Breed

The Cambar was originally developed (in the 1920s) from a cross between the Barred Plymouth Rock and the Campine as one of the first 'Auto-sexing' utility breeds. The female looks quite similar to the Campine.

The chicks exhibit clear colour differences on hatching which is a great bonus when deciding what to do with them. The females having dark brown black colouring with small white markings on the back of the head. The males have a straw-coloured head/background.

There are two variants - the Gold and Silver.

Cambars are a utility breed - good for both eggs and meat. The eggs are pure (matt) white and can be good layers. They are generally inquisitive and if handled early can be very friendly.

Hope this helps,

Wayne

here another one thats worked for me so far. dunno if it always works

Light sussex roo with yellow legs (must have) x silkie cross breed hen that has black skin

resultant chicks,
cockerals will have yellow beaks and a yellow cere,
pullets will have a black beak and black cere

As i said i dont know if it always works, it could be the other breed in the silkie and whatever has made the sussex roos legs yellow.

Also found this at Classroom@The Coop:

http://www.the-coop.org/cgi-bin/UBB/ultimatebb.cgi

The following is in reference to chick down with sex-linked barred.
Autosexing Breeds:

quote:
--------------------------------------------------------------------------------
This light patch is very similar in chicks of both sexes having black down, but when the barring is transferred to a brown down there is a marked difference. The light head spot on the female chick (one dose) is small and defined, while on the male chick (double dose) it spreads over the body…….


Cambars were created by taking a sex-linked barred bird and crossing it to Campines. The hybrid was backcrossed to Campines several times and then sex-linked barring was brought to homozygousity.

They auto sex more accurately than Barred Rocks. They are a combination of autosomal barring and sex-linked barring. Two copies of sex-linked barring in male chicks can be distinguish accurately from a single copy of sex-linked barring in females on the autosomal barred down pattern of both gold and silver Campines.


You can find a section on Cambars in Hutt's book, Genetics of the Fowl, 1949. He has a picture of the chicks that illustrates how they are sexed.

Go to this website: http://www.autosexing.co.uk/

If you go to my pics in the photo gallery you will find a scan of a page from a book by Katie Thear published in 1987.

It lists a lot of possible sex linked crosses.
