Help in identifying this pest on feathers?

You're dealing with cold/freezing temps, correct?
I wouldnt spray birds in cold temps nor inside their coop when there is a threat of cold or freezing temps.
Permethrin dust and Sevin dust are cheaper.

The bedding would no longer be suitable for composting with the permethrin in it correct?

Here you go, scroll down to "Permethrin in the environment," and/or read the whole link:
