My broody hen had 5 Silkie babies on May 7th. Since then I made a special place for her on the bottom level of our coup so she could sleep with her babies at night. Tonight when it was dusk mommy decided she was done with sleeping with the babies and went to the top of the coup leaving her babies to sleep alone. So I grabbed her off the roost and put her with her babies and she is still avoiding them. Will they be too cold tonight? Should I move them to the top level of the coup or bring them inside and put them under a heat lamp. What should I do??? They are so little.
