I have 2 seperate flocks of chickens. 1 is 1.5 yrs old and the new flock that is kept in a seperate place is 3.5 months. The problem is with the 3.5 month olds. I went out to feed today and noticed what looked like red mucous in their poop. It wasnt bright red. I accidently fed them some cracked corn that had mold in it a few days ago and wonder if that would cause it. They seem just fine. Please HELP, I dont want to lose my babies!!
