Would it be possible to borrow a rooster for a month to fertilize my girls for chicks? Or would it be to stressful to only have a roo for a short time? How long does it take for a hen to get comfy with a roo to let him do his business? How long after mating is a hen fertile for? Sorry for all the questions. I dont have a roo. I live within city limits and can have chickens and I dont see where I cant have a roo but my hubby would rather me not. But I am sure he would let me "borrow" one for a short time.
