I have a few chickens that think they are turkeys. They roost at night in the trees with the turkeys. They follow the turkeys all day long and ignore the chickens....These were chicks that were raised by my Turkey hen... When she hatched out a clutch of turkey chicks in September, one of the chicks saw her and went running to her "mother" only to be run off by her. I felt so sorry for the poor chick.
I am not sure what I will do with the one chick, she is close to laying age now and refuses to go into a coop.
