Chickens missing tail feathers and skin irritation

[Mjoycerd]

Hi,
I am new to site and was wondering if I could get some help identifying what issue is causing all my chickens to not have tail feathers, missing other feathers and irritated skin. I’ve attached some pictures.

They have a dust bath and I have tried using the poultry sprays, thinking it might be mites.

They are still producing a good amount of eggs but do seem irritated by this, of course.

Any help would be appreciated. Thank You!

Michael

Which poultry sprays have you used?
What's their diet and space size?

I tried Premo Guard poultry spray from Amazon. I have 10 hens and they have about 100 square feet inside and out and I also let them free range in our large backyard for a couple hours about every other day.

They have been eating Cluck & Co. organic layer blend chicken feed from Tractor Supply. I started to slowly switch to Nutrena nature wise harvest blend egg layer feed. This problem has been going on for months, it did not start when I started switching the feed.

Thanks

You're going to want get a permethrine based spray or powder, unfortunately , natural products aren't quite as effective with mites.
I believe the new feed is 18/20% protein? Feather loss can also be a sign of low nutrition diet, cluck and Co is organic but the layer has mediocre nutrition, not much better than dumor
