I had a lot die like that this Summer. It was not cociddiosis (sp). I think it was some kind of bacteria? Jack lost a lot that way too. We both lost a lot of Wheatens; Jack- Marans, and me - Ameraucanas. We think the breeds with narrow bloodlines are more susceptible to what even it was because my Ameraucana chicks that are Wheaten/Blue crosses all survived but none of my pure Wheatens! I don't know if I want to cross those 1/2 Wheatens back to my pure Wheatens and strenghten the bloodline of sell all my Wheatens. I feel pretty busy with my 2 Cochin projects - Self-Blue and Mille Fleur. I will NEVER give up my Cochins but those Ameraucanas sure are pretty.
I had trouble with Isbars from February until August with the exact same type of problem, I would lose all the chicks one at a time from 3-4 weeks. If I was really careful and dosed them with Tetroxy HCA I might manage to save one out of 10-15. Did OSU testing and found out the hens were passing e. coli bacteria to the chicks through the eggs. Poor things didn't stand a chance. Had to get an RX from a vet to cure the adults, Bactrim. Just as I finished up the Bactrim regimen a neighborhood dog got into my yard, ripped their run door open, and killed my rooster. Of course.
Thank you! It's good he's only been raised around chickens, too. The Guinea we had for all those years was a lone Guinea also. He had no idea he was a Guinea until i got 5 more when he was 11
