That's too bad! Glad your other one's are doing good, though!I got me a tub of rooster booster a while back when I found crooked toes on a pullet. I only use it on chicks for about 6 weeks so that tub will last a while.
the chick did pass yesterday. to me it looked like a congenital problem. it was sad but these things do happen. all its siblings are doing well.
