i hatched 4 chicks out of 5 eggs set 9/7/2011 4 black and one lil white one. one of the black ones never hatched but was fully grown with the whole yolk sac absorbed. While candeling I dropped one egg on the small end. I put it in the steam incubator anyway and just watched it. 3 lil black ones hatched on their own the white one i helped out. one of the lil black ones was walking funny this morning so i checked him out. It had a dried string holding its foot keeping it from being able to walk, and from its ambilical cord its yolk sack was coming out. I euthanized the poor lil chick. The white one I am worried about because it is a lot smaller than the black ones, and it keeps its head low. it is just not acting like the others at all. do you think dropping the white one caused some kind of brain damage? I am posting another question regarding cleaning my incubator.
