I have a 5 week old NN chick. Her legs are not working right, I would not say paralyzed because she can move them. She can not walk, holds them out kind of stiff but when I pick her up she can fold them in. She also has bloody poop it has been getting more and more bloody with each poop. And kind of large for a chick her age. She is on medicated chick starter and water, occasionally I put vitamins in the water. Before I separated her she was in with a bunch of other chicks of varying ages all about the same size in a playpen brooder with pine shavings. If I can't save her I need to know if the others may have a disease, the last few days I have been watching them close and they all see healthy and fine. PLEASE HELP!and THANK YOU!!!
