So about a month ago, I buried about 1 hen and about 5 chicks ( 2 silkie, 1 americana, 3 turkens) then, I bury a 3 months old turkey a few weeks ago. Yesterday, I come home to find my peachick dead and now tonight I just found my favorite 5mth old silkie dead I don't understand what in happening, I do free range them and they stay in my yard ~ They all seem in to be in the same position when I find them minus the turkey ! They are fine looking and then the next thing I know they are laying down in a way that makes their necks look broken and they are gasping for air and then next thing I know they are dead ! WHAT IN THE WORLD could be happening ???? I've tried searching on the internet at the symptoms but, I can't figure this out - So does this mean all my other chickens are gonna die too ?????
