one of my hens has what looks like a salmon coloured run in her poo.. theres always brown in her poo.. but today was what looked like a 2" long piece of twine in it.. but it was poo for sure.. I just dont get it! also - 2 or 3 piles of yellowy diarrhea... What can cause it.. and other than dustin the coop & food with DE... what can I do about it? THanks!! I've gone from 22 chickens & ten eggs a day to 30 chickens and 5 eggs a day.... was getting 10-11 eggs a day, then one chicken died in a nest box and from that day on have gotten 5 eggs a day.. So those are normal? .. the two photos are NOT from my chooks.. but that's what i'm getting!
