I am hopeful that two at least will survive. They are now eating and drinking on their own today and can stay upright. A third is looking better today and can remain upright 50% of the time. The fourth still cannot get on its feet, and when I set it upright can't hold its head up. But its eyes are getting clearer and it's chirping. I am not used to seeing weak chicks on the brink of death recover like this. But most of the weak chicks are weak under ideal conditions. These 4 chicks were the strongest of 40 and the only survivors of the Styrofoam holocaust. When I put them in the brooder, they were seriously completely limp, immobile, and barely breathing. I was so certain they were dead or at least brain dead. Their will to live is truly admirable.
