I am at a loss......I have 7 chicks born in my incubator 12 days ago. All are doing fine, eat, drink, run, sleep, stretch and grow. They are inside the house in a 40''x 40'' wooden box under a red heat lamp; temperature is fine. They have lots of room. I read all the forums and discussions on pasty butt for help. I put ACV in water and change the water many times a day. But this last little one is not growing, I constantly have to clean his little butt multiple times a day over a bowl of warm water with cotton ball. I have tried giving corn meal three times which they devour and it has helped the little one. I have tried a cooked mashed egg which they did not touch at all. Should I give more cornmeal? Will he get better? I don't know what to do anymore...loosing it...so worried.
