Hello We currently have 14 layers...well now it is 13. We lost a hen over the weekend..her comb was all scally and shruken. Is it possible the group of the layers have avian pox?? Several of the ladies have a few black spots on there comb....they are active and otherwise healthy looking... If they do have it, where can I get the medication to help get rid of it? And are the eggs still okay to eat? Thanks Sara I love this site!
