We had a beautiful broody Pekin hen, Rainbow who hatched out 3 chicks recently. Sadly last weekend badger broke into our broody coop killing Rainbow and 2 of the chicks. We had an orphan, Custard, 2 weeks old. He/she was on her own and cheeping constantly. My 7 year old daughter spend the entire day hugging her but when it was time for her to got go bed, Custard was distraught again. So we took chance and put Custard in a darkened coop under one of our Silkies ( who are always broody). We knew it was not a great chance of adoption as Custard was 2 weeks old, but the Silkie made all the right noises and it seemed to go well. All the next day we listened and took the occasional peek and all was well. We were elated. Then on the second day, after 36 hours we decided to lift the blanket and allow light in. The hen went crazy and tried to attack the chick. This was terrible as I was trying to leave for work and we were getting the kids off to school. My husband suggested we darkened the coop again and popped the chick under. We did this, with success which surprised us. That was 3 days ago. Both Mum and chick are happy in the dark but we are too scared to lift the blanket again. Any suggestions?
