Buff Sebright breeding questions

[britesidefarm]

I have a Buff pullet who is around 26 weeks now. She hasn’t layed yet, but I’m assuming she will when the days get a bit longer. I understand that when you cross a Silver cockerel to a Golden Pullet, they are sexlinked and all females will be silver whilst males will be gold with silver leakage, but what if you cross a Buff pullet to a Silver cockerel? Will it be similar?
Here’s my pair:

I'm not sure, but here's lots of people on BYC who are good with genetics. They should be able to help. I just wanted to say those are beautiful birds!

Thank you! I’m attempting to breed this cockerel with some pullets we hatched along with him that have some nice lacing, to try and show in the future.

That's backwards.

You need a gold male ("Golden" or "Buff" would both work) with a silver female to get sexlinks. The chicks will be gold daughters, silver sons.

It's the same gold/silver genes used for the common Gold Sexlinks, ISA Browns, Golden Comets, and so forth. They all have gold females (gold, red, brown, are all "gold" for this purpose.)

Hm... I just thought it was Silver x Gold =silver pullets because of this thread from 2009-2011

For sexlinks, gold father, silver mother to get gold daughters.

To get silver females, use a silver father, but then you cannot sex the chicks by color.

Sons look silver either way (maybe with leakage or yellowing, but that shows up more when they get older, not when they're tiny chicks.)


The reason is that the male has two Z chromosomes with the gold or silver gene on each one. He gets one from each parent. When he's got gold from one parent and silver from the other, he looks silver because silver is dominant.

The female has only one Z chromosome. She gets it from her father, and passes it on to her sons. So whether she is gold or silver is determined by her father, with no input from her mother. (She also has a W chromosome from her mother, that she passes to her own daughters, but it does not affect the gold/silver genes.)
