Not sure if this is the right section to post this??? Let me know if it is not. My hens are eating chicken poop. there seems to be one or two of them when they poop the others swarm around to eat their poop. some peck at the exit door where it comes out. Is this normal? I was thinking that maybe they are eating the corn that is not being digested? Any help would be appreciated. I am worried there is something wrong with two of them. Could they have worms or something else? Thanks!
