If a hen carries the brown dilution gene, will all male offspring recieve a copy?

Yes, all male offspring will receive a copy. But it shouldn’t affect their appearance as it’s recessive and one copy isn’t enough - males need two copies of chocolate to appear chocolate (I assume by brown you mean chocolate).

Wandering if female offspring fron a hen with brown( chocolate )dilution gene, will receive the gene.

Thanks

No, the female offspring will not receive a chocolate gene from their mother. Their mother has one copy of chocolate only and it always goes to her male offspring, never to the female offspring.

If female offspring have a chocolate gene they have got it from their father.

Another breeding scenario:
Drake with extended black and 2 copies of the chocolate(brown) dilution gene. So he is visually a chocolate coloured bird.
Duck is heterozygous for dusky, no extended black or chocolate (brown) dilution genes. She looks dark mallard like dusky with eye stripe.
Is there any chance a percentage of male offspring will receive extended black and two copies of chocolate from the male parent?
Or does the female parent need to carry chocolate gene in order to breed a visually chocolate drake.
Ie a copy of chocolate from duck and a copy from drake.

From that cross you will get black birds and chocolate birds. All the blacks will be male. All the chocolates will be female. So you’d know the sex at hatch.

The mother would have to have a chocolate gene (ie be visually chocolate herself) to produce chocolate male offspring.
