Hi, my chickens aren't doin well at all! they are eatin and drinkin but have diarrhea and one is loosing its back feathers. they haven't started laying eggs yet so i wanna fix the problem before the start laying. some of the are skittish but most are friendly. i clean my coop once a week and give the fresh food and water in the mornin. Any ideas on what might be wrong with them and how to fix it? i have been really concerned about them and am trying my best to help them. thanks
