Ive got a 2-3 day old barred rock chick that is not doing well. Lethargic, a little uncoordinated, peeps constantly. Baby is not eating - drinking, but not eating. Poops normally. It is smaller than the others, so I have her separated in the brooder so she doesn't get trampled. I've been hand-feeding it a mix of egg yolk and sugar water in a syringe - tried to hand feed it some crumbles soaked into a mush, but baby was not interested. Not sure whether I should continue feeding it the way I am, or just let it go?? I know a lot of these just don't make it, but any advice would be appreciated. If I should keep feeding her, how often and how much?
