I dont have a clue what is going on. 8 Ameracaunas and 3 banties .Chicks hatched 7/9. Put in brooder with chicks hatched the week before. 1 dead when I woke up this morning. Another weak and dead within 30 min. Another one weak this after noon and dead at 730. One weak in my hand right now. Whats going on? And its ONLY the Ameracaunas. No one else seems to be affected by whatever.
