I have a 15 day old cochin bantam chick, and she has a pretty bad crossbeak. She was doing alright eating powdered chick feed, but now she just has to much trouble. She is not growing with the rest of the chicks. I care too much to let her suffer because I am too busy with high school and my job to feed her. I read that you could give them Benadryl then snip off their heads when they are asleep, but I am too squeamish for that. If i give her a good dose of Benadryl, will that just put her to sleep for good?
