Thanks for the info. It's still eating and drinking but the others are already getting noticeably bigger. It does have a poopy but and I keep cleaning it. I do have the electrolytes.
So I have 1 chick that is 10 times louder than all the others. It chirps continually even when it's asleep. Seems happy and acting normal otherwise. Is this any indication of it being a rooster or that it will be a loud adult bird????
