Well I have one last hen and the Roo got killed from my GSD Yesterday so unfortunately Its very sad sense this is my first brood of chickens that I raised. Now I have to work with what I have, which is trying to make my one hen broody so that way I have a chance with the fertile eggs that the Roo fertilized before he died last night. Please give me tips. She has never laid on her eggs so she is a newbie. O yeah how long are the eggs fertile after the last insemination, a week?
