Last night I had 7 peeps hatch (in the incubator) I was SO excited. However, 2 of them after hatching, never got up, they just laid there and today they finally died. 2 of the others seemed ok, I moved them into the brooder, but they aren't doing very well. 3 of the other peeps seem great. What would cause this? They haven't started drinking yet, but should I give them some water with vitamins and electrolytes or poly-vi-sol? This is the first time I've hatched out eggs, and I'm broken hearted.
