I have 70 feathered chicks who where moved outside two weeks ago. Until day before yesterday everything was fine now there dying! I treated with tetracycline when the first pullet died and everything seemed fine so I thought it must be okay because sometimes you just loose one in a group so large. Well today I went out and there are 20 deaths and lots of chicks sick! I cant take them to the vet because it's sunday so i need idea's of what is going on and a way to keep them alive till Monday! One or two do have bloody stool so i was thinking maybe coccidiosis but almost all of them DON'T have bloody stool.
