I just picked up my 12 chicks from the local co-op. They order from Ideal. I got 3 Black Aust. 3 silver laced wynd. 3 EEs 3 speckled sussex. The speckled sussex are small and are not sure on their feet. One is very weak. It will drink and kinda eats. I have them in with the rest for warmth. Does anyone have any ideas as to what I can do to help them get better? I really do not want to lose them.
