I have a week old chick who, until yesterday, was perfectly fine along with her 6 friends. The babies stay in a "shelf brooder" in the house for now and there isn't much to get hurt on, but somehow this little thing hurt her leg. I have no idea what is wrong, other then that it might be swollen. She will not put any weight on it. I see no obvious cuts or abnormalities. She moves around on one leg with the help of her wing with ease and is eating, drinking, and pooping normally. She is not making any noises indicating she is in pain, she isn't shaking, (unless I pick her up to inspect her.) I am unsure as to whether I should just leave her alone or cull. My gut is that she is making it around fine, does not appear to be in pain, and is eating and drinking. Any advice, validation, help, opinion, is welcome. I don't want to prolong the inevitable nor do I want to cull unnecessarily.
