Isolated one week and giving electrolytes with added vitamins by dropper. Got in touch with supplier, all her chicks are healthy as are two others I obtained and raised at same time. Doesn't drink on his own, will eat a little. happily eats hand fed meal worms (live). neck feathers ruffled. sits or stands in same spot, little moving around. Has always been less dominant of the two roosters, but in week prior to depression / huddling, his brother was clearly becoming more dominant. He seems thin, but no signs of sores or unusual anything. Eyes normal. No other symptoms. Any help would be appreciated.
