Try calling animal shelters, sometimes they may have people that have asked about chickens or people that work there that have farms to take them, the shelter where I worked did take in chickens when they had room or people working there could take them home, worth a try....or they may know of some help to rehome......hope it works out for you....They are on craigslist, on freecycle, facebook. you name it.
So in essence, we have to kill these birds who we hatched from eggs? Anyone want to tell my son that? I don't. And exactly how do we kill them?
