Could someone please offer some advice on this problem? We have 30, two-week old baby chicks of a variety of breeds. About four days ago, we noticed that one of the female Light Brahmas was acting lethargic and was very wobbly on her feet. This progressed for another day until she was unable to stand up and just fell over when she tried to walk. We moved her to a separate little brooder box and are maintaining the temperature as it was in the main brooder. She has food and water available within a few steps, but she doesn't seem able to get to them. My husband hand feeds and hand waters her every two hours. We have a little bit of sugar and the correct dosage of terramycin in her water. She is eating Purina Mills Start and Grow Medicated feed. Her legs don't seem paralyzed, as she is able to move them. I can't find any external damage to her legs, no sign of mites, and joints and leg size seem same as the other Brahmas. There are no broken bones and both legs are behaving the same way. Other symptoms that have come and gone: 1. She started out four days ago with very runny, dark brown, diarrhea. This changed to soft, green poo yesterday. Today, poo is almost normal looking/solid, but still with a bit of a greenish hue. 2. Her eyes seem watery and her voice is a bit hoarse. 3. No discharge from nose. No sneezing. 4. Very lethargic, sleeps almost constantly. Falls asleep during feedings but wakes up to take a bite here and there. 5. Two other chicks in the main brooder are acting funny, huddling and scurrying on their haunches, rather than standing upright fully. When startled, they will stand up and appear to run normally. But when they're calm and just moving around scratching to eat, they stay huddled low on their haunches. As mentioned, this is only occuring with two other chicks (an Araucana and a Speckled Sussex). One other chick in the main brooder has diarrhea, but I can't tell who. 6. The sick Brahma does not have Spraddle Leg, as she is able to hold her legs underneath of her, they do not splay out to each side. They just seem incredibly weak! I have tried to give as many details as I can think of, please ask if more info would be useful. I sure hope someone can offer some help, we are just heartsick that little "Carrot" is suffering and unable to walk. Thanks in advance for your help.
