I have a broody bantam cochin that successfully hatched four babies, she also has a silkie that is helping her sit and tend to her chicks. They are both being good mothers co-parenting. I have food and water right next to them. There is 2 roosters with them and a few other hens who are not being agressive or anything. All seems to be great. The chicKS are 4 days old and both mom's are still sitting on eggs. Well, here's the scoop.. I have an automatic coop door and it did not close last night. I found two dead babies outside in their pen. They were cold and stiff. I don't understand how they died. They were no injuries . Is it possible they couldn't find their way back up to mom and froze? It was only in the upper 70s last night. Why wouldn't mom go to them? Why did she ignore their cries? Is it possible the others chickens threw the babies outside or something? Should I take the remainder of the babies from her or leave them? Also why is she still sitting after four days? I apologize for the cluster of questions. My husband thinks the chickens did this and wants to bring them in. I don't feel like the chickens caused this.. I feel like they wandered too far and couldn't get back. Thanks all.
