My mama hen is sitting on the eggs and three chicks now. We have separated them from the rest of the flock and put her in a crate with food, water and a heat lamp. Is the mama hen gonna be ok and able to sleep with the heat lamp next to her. It's not directly on her it's next to her. Should I turn it off? I don't want a chick to come out at night and not be able to get back under mom and die. Basically im asking if the light will effect the mama hen? Thanks. Any response is appreciated
