I need help, my chickens are starting to die only days apart. So the first day three of my chickens died, showing no problems the day prior. Just one day alive next dead. Then a day later another of my chickens died, same thing. Showing no problems prier to death. Then a few days ago one of my chickens did show problems, she was having problems with the reflexes in her feet. Like it took a while for her to figure out how to place them. Then I went out this morning and she was down, she couldn't get up whatsoever, when I tried to pick her up she wouldn't close her wing. It was completely tensed up. Does anyone know what's happening. Someone please help me!!!!
