My little week and a half old chick has been doing great all week, then all of a sudden yesterday, it was lying down on the ground and not getting up to eat with the others, and its eyes were very heavy. Today, he is so weak that he can barley get up and he has just been lying down all day. Is there any hope for him at all ? Can I do something to make him feel better? How could this have happen ? The only thing I can think of is that sometimes they poop in their waterer and maybe they drank so poopy water before I cleaned it out. Another thing I did was feed them some worms from my garden but I have been giving them some little worms since they were like 5 days old and all the other chicks are doing just fine.
