Hello, new to the forum. I wasn’t sure which forum to post on. I would appreciate some help and advice. We have three age groups of hens/pullets. The one group of 8 hens are about 15 months old, and another group of 2 hens started laying around three months ago. A month ago a dog got into the chicken run and attacked the hens. The dog killed one of the older hens and seemed to pull a small amount of feathers off of a few others, one being a younger hen that started laying three months ago. All hens stopped laying three days after the attack. The older group of hens seemed to be molting and also winter has set in the same time as the attack. It has been a month and the two younger hens have still not laid. Is this winter related or dog related? Anything I can do?
