I've had my ex battery hens for about two weeks now. They appear to be doing great. They are all eating, drinking, gaining weight and their feathers are growing back. BUT they have had runny poop for the last week. These are my first hens so I don't really know what could be causing their runny poop. I am feeding them layer pellets and rolled oats, they get fresh water every morning with apple cider vinegar and tonic in it. They have oyster shell and grit available and meal worms as treats. They have been wormed and de-loused. They are free range during the day and in the coop at night. I'm worried it's to do with what I've been feeding them because I've been getting conflicting information about how much layer pellets to rolled oats they should be having. Any advice would be greatly appreciated, I've gotten very attached to my little ladies and don't want them to be unwell.
