Hello I have a broody hen who seems to be unbrooding. Every night I am having to force her back on her eggs. She goes to go to bed with other hens and her feathers aren't all puffy no more.. When I get up she runs right off the eggs and stays off all day now. She has 9 eggs she has been sitting on for about 16 days. Could I put them under a heat lamp( I have the red one with reflector from tractor supply) in the house? I have candled them and they are still viable.
