I have twenty-six, fifteen week old chicks. They all seem very happy and healthy, yet there are sooo many feathers laying around the coop, run, and everywhere! They free range all day from about 9:30am til 8:30pm. Every morning there's lots of new feathers in the coop and run. All different kinds, big ones, medium ones, small, fluffy ones. And from all the different breeds too! I know they go through a few juvenile molts, and it's been really hot here in E. Texas. Should I be concerned ? I don't see any bald spots on anyone, or anyone acting sick. I'm new to this, just been doing it for 15 weeks! Any thoughts would be appreciated. Thanks!
