Does anyone have a solid idea of what this is? My whole flock (was 13 hens and one rooster, down to 9 hens and my rooster isn't looking good.) I have tried everything I can think of. Deworming, treating for cocci. I don't know what to do! I lost 4 hens in just under 10 days and now my rooster is acting like he's on his way out. He is barely a year and absolutely the sweetest, most fellow. Any help is appreciated.
