I have a bantam rooster that can't stand. If I try to stand him up he falls on his head or side. I have been hand feeding/watering him for about 4 days. This problem started out slowly; at first I thought one of the other roosters hurt him because he could stand and walk but he was quite wobbly. He has progressively gotten worse. He eats as long as I feed him and his poo looks pretty normal. Is there anything I can do for this little guy?
