Hi! We have 8 hens, all are about 24 weeks old. Lately, we've noticed that there are lots of feathers around the run. What's odd is that the chickens don't seem to be missing any feathers. They look great! I've checked for parasites...they have a dust bath and they are healthy. We do live in Texas so it is HOT here...they have a fan in their run. I've read that feather loss can be caused by stress...what are other indicators of this? They all get along great and have a ton of space to roam, so not sure? Should I be concerned? We also only have one hen that has begun to lay...aaarghh!
