Egg fertility question

[chickengeorgeto]

I read research recently that suggested a hen may be able to accept or reject sperm from specific roosters to make the father of chicks the preferred parent.
I'll see if I can find it for you.


That's not how avian reproductive systems work. First of all, it doesn't take a few weeks.

I have seen yards of 1,500 roosters where they were all on string walks or tethered and there will always be a favored roosters or two on these yards who will, lets say get the majority of the action.

The healthiest roosters' semen will also remain violable longer imho.

You guys are right on target. We put the rooster with the young hens on 12/21 and today’s eggs were fertile. Thanks for everyone’s help.

and some were probably fertile yesterday.
