I had a hen hatch out chicks. When the chicks were roughly 30 hours old mama took her babies outside. One couldn't figure out how to follow her, and I found it dead in the box that morning. I went to pick it up and it wasn't dead, it was barely alive it was opening its mouth but the body was completely limp. I ran it inside I heated it up and after about an hour came back to full health. I nurtured it until it was healthy enough to go back with mama. The chick was with me about 12 hours. When I went to give it back to mama the baby chased me out of the coop screaming! I took it back inside and I realized it imprinted on me... Other humans it doesn't care about. If it can't see me it screams and chirps loud! I tried again to put it back with mom but mom didn't want it, and the baby wanted me. So now I have this chick living in my house with me and it thinks I'm mom... Anyone else have this happen?
