We FINALLY got our coop complete this afternoon...as I was putting the girls in....they were checking out the new digs....I saw a couple of them a while later, eating loose feathers that had fallen out of somebody...they were just chowing down! I was horrified!!! Is this normal? I know that they did not pull them out...I have been seeing them lose a feather here and there while in the run.....your advice and help is greatly appreciated!
