I hope everyone had a good holiday. Well, I came home from vacation and found three new chickens in the chicken yard! The yard is next to open land around my house. Apparently someone dropped them in the yard. I had a nice young man caring for all the animals. He did not notice the new pullets. I was gone for ten days and do not know how long the chickens have been here. Is there any point in separating them now? They stay away from the other chickens, but do roost in the coop.
