Ok, at first I thought it was just pasty butts, so I took to soaking rear ends in Luke warm water... Chicks still dying. I've lost around 95% of the chicks I've hatched. They seem fine one minute dead the next literally within hours. I've been told by the owner of our local co-op that it sounds like coccidiosis given the chicks go from healthy to lethargic, unsteady, flu-ish (some have been sneezing with runny eyes etc) then dead. Most have also had the poop build up on and around their vents. One I cleaned off very gently and as soon as I set him back down he fell over, stretched out and died. The co-op owner recommend an antibiotic other than the duramycin I tried before that's specifically intended for coccidiosis so I'm trying that. It's only been 24hrs but we have only lost 1 more, the other that was doing badly hasn't gotten better but no worse either. All my babies are kept in the incubator for approx 24 hours so they are 100% steady dry and warm before moving to our brooder in my bathroom under the heat lamp, I also have a heater in there for extra warmth given the below freezing temperatures at night. The bedding was pretty dirty for a few days due to a financial emergency but has been kept clean and dry, changing water every day, I drain the available water and put the remaining back in every few hours, fresh feed every day. I'm keeping all the new hatchlings in a separate unused brooder to prevent further infection. I'm so lost! It more started with eggs that were shipped, I made sure to only order from certified flocks.
