Yesterday my husband found one of our 6 week SLW's dead in the larger brooder pen that we have. Then this morning we lost 3 more SLW's and 1 of our Black Jersey Giants. THey are all the same age and in the same pen seperated from the other chickens. I noticed that there was bloody poop on the ground and started doing some reading and i think they might have Cocci. I ran to TSC and got some Corid and started treatment. Got home later this evening and went to check on them and they all seem very sick but all were alive. Went back about a hour later and found another SLW had past . I am so afraid that i am going to lose them all. Is there anything else i can do, is it to late?
