Does anyone have any tips on sex linked cross breed gender ID with buff orpington x Speckled sussex? i do not know which breed was hen and which was rooster.
I was sold two buff orpington chicks but they are looking like they are crossed with speckled sussex...they are 4 weeks old now and starting to look quite different from each other in colouring/wing pattern..so i am thinking one is a pullet and one a rooster...i will take and post some pics tomorrow!

I don't think that mating would produce sex-linked chicks either way around, but I may be wrong.

I shall look forward to seeing the photos as I used to keep orps and sussex!

Please find attached the pics i took today of my chicks. It is hot here and they didn't like having their photos taken, hence the open beaks etc! Im very interested to know people's thoughts as i thought buff orpingtons were pure gold in colour. Thanks again!

I don't think you'll get sex linked progeny from that cross. Also the speckles on the Sussex are inherited as a recessive, so in a a cross should disappear.

I suspect you're not looking at a simple cross here.

Hi, well they obviously aren't buff orps - you were quite right.

Actually they look a bit like jubilee orpingtons, but I can't see the black markings (ie black bars on some of the feathers before the white tips) they should have and in any case I don't know if you have them in Australia. My guess is that maybe they are pure bred speckled sussex (although I can't see the black markings, but that might be me not looking hard enough). I say this because the speckling requires 2 copies of the mottling gene to show itself. In addition, orps don't usually reveal themselves so clearly to be male and female at 4 weeks, as I agree, going by the comb you have one of each.

And that is interesting that you suggest pure bred speckled sussex, as i was also sold two of those but they look quite different :roll: , they are the same age 5 weeks, i will attach a few pics

OK, I am now confused. The chicks do look look buff orps, rather than SS.

Virtually all the birds look the same to me in their colouring except (some) of the sussex have a lot more white on them and none of them look well marked for SS, but this may develop. The excess white may moult out as they are juvenile feathers or it must just be that the birds have parents who have thrown badly marked offspring (ie too much white, which is known as 'hysterical mottling' on a mottled bird in the UK!) In the last picture the bird on the left is either younger than the one on the right, or it is most likely a male as it is slower to feather.

When I enlarge the photos I am really not sure what I am looking at. The speckles are very blotchy and there is a lot of white. I am really not sure if these are PB sussex, or something else. I think you may need to grow them on to get a clearer picture of the feather pattern.
