My one month old chick, whom I hatched and thought was fine, started developing a swollen joint on its right leg. A week later, both legs are twisted and contorted. I dont know why? All other five chicks from different mothers are fine. The two other chick that hatched from this same chicks mother both died after just one week. This one has survived so far. Does anyone know what might be happening? My fear is the older it gets, the more weight on the legs. "Fry" eats and drinks fine, can move around with much struggle, and will move toes, but can not keep up with other chicks. Thank you for any input.
