We finally have our first baby chick, it hatched today successfully. There had been two eggs in the box. The first egg got "crushed" or trampled, we're not sure by which chicken or why. The second egg... when it started hatching we brought it into the house and carefully watched it and kept it warm. When it got to being nearly hatched we placed it back in the nest with just the broody hen, and barred the other chickens from coming up in the nest. The broody hen seems to have bonded with the baby. She seems to be "scent marking" it (she will rub a gland near her tail and then gently nuzzle the chick) and keeps it tucked under her belly. We have 3 other hens and a rooster. Should I be concerned for the baby chick tonight? Will the rooster or other chickens try to kill it?
