I have four young hens (about 2 1/2 yrs old) who were attacked by the neighbor's dog about 3 weeks ago. We lost one to her injuries and another lost a few feathers but no injury beyond that. The other two were unscathed. For about 2 weeks after the attack, none of them resumed laying. I assumed this was from the trauma. However, the only one of the 3 who was injured has quite recovered, but only one hen has resumed laying. Any ideas? I know the colder weather can have an impact, but even when it's very cold, these hens usually lay every other day or so. If it helps, one is Australorpe, 1 is a Buff Orpingont, and 1 is Barred Rock (the rock is laying daily. Could this still be a result of the trauma or is there something I should be doing? They are free range but confined to their coop at night.
