I am no expert by far so my idea may not work. Chickens get restless and bored. Have you tried hanging cd disk so they can play with it? There are many more ideas here. I have a RIR named Gladys and she's always been very vocal; it's enough to drive you crazy! So I get your frustration. She does...
I would offer it now. Chickens instinctively know what they need. Make it available for them in a dry place. In my coop I have like a feeding dish with 2 compartments. It screws into a wall. Keeps it clean as long as its above the breast so nothing gets flung out and no poop accidents in the dish.
I ad a vet checked for worms. They are free of worms. There are some formed stool with the diarrhea.But the problem has not been fixed. I tried mixing yogurt to the scrambled eggs after it was cooked. Nothing seems to help.
My BR girls crown used to stay straight up; now it's top over a bit and looks like ribbon candy. She's 8 months old. Does anyone know if it's a problem? Do combs change in them? Babs needs to know cuz the other girls chuckle at her...lol
