What is the suspected cause of the leg not working issue? I found a Cornish cross that couldn't move either leg at 3 weeks old, it died 2 days later but was still eating and drinking a bit. Then another with one leg not working at 4 weeks. I separated the second one so it had food and water right in front of it, but the next day, both legs were not working, just stuck to its belly even when held upside down. 2 days later it was done eating, so I shot it in the head and its legs kicked like crazy. I thought it may have been a stroke? Is leg failure common or do I have something else going on. I take food away overnight to slow down over-eating but they act starving in morning. They are outside now and I spread there feed over a 100 sq. ft. area to make them move around while eating and take longer to get full, but they eat all day. I lost 3 at 2/3 days old then the other 2 at a few weeks old, seems like 5 lost out of 14 is pretty high casualty. I fed medicated feed to vaccinated chicks, could that have caused these problems? They are looking pretty tasty at 5 weeks old though.
