I have a 3 day old chick who stands and walks for a few seconds and then crouches down and rests its head on the ground. It has not eaten as far as I know, I have tried hardboiled egg yolk. I have dunked its beak in the water but the bird does not do any of this on its own. It had a messy butt but I cleaned it and applied vaseline. It chirps and runs around but not for very long. What could be the problem?
