We just got our 12 Red Stars 2 weeks ago, they were laying the day we got them, they are 10 months old. BTW, I come to this board ALOT to learn things, like how to build the coop etc. So they came with hog rings through their beaks and a green blinder tag through that. we took all the blinders off, and plan to take of the rings. So, therefore I have held all the hens, did that last weekend, but today when I thought they were looking thin in the keel, I picked several up and they are quite thin. They get layer meal, kitchen scraps, and range during the day. What do we need to do? thanks!
