Hi! I've had chickens for years, no problems. We hatched some chicks about 2 mos ago from our sizzle rooster. We have a barred rock/sizzle who is so cute. Two days ago she started having weird leg spasms. It was 107 here in CA and I thought she might not be handling the heat. She is doing it today still, falling over and legs shooting out in weird directions. They have lots of shade, water, frozen corn/strawberry treats through out the day. Only one chick is doing it. She always has extra toes but that has never bothered her...any ideas??
