I have a 8-9 week old Polish the loses it's balance and can't seem to stand or walk for very long without falling over. I got him along with two other polish chicks and the others seem fine. He is eating and drinking and there are no signs of injury. He has been like this for almost a week where some days are better then others like yesterday he seemed to be getting better but today he is worse. I have been giving him vitamins for the past two days and making sure he has been getting plenty of water.
