I have 8 chicks and a broody hen that developed bloody poop about 6 days ago. 4 of the chicks are 4-5 week old silkies and the other are 4 banties with their momma. They were in the same space but seperated by wire. The temp coop was ourside, uninsulated and with a small heat lamp would stay at 14-18 degrees. unfortunately temps dropped and that is when they developed the bloody poop. The 4 chicks with the momma were hunched over and puffed up but were still active, ate and drank well. the 4 silkies had bloody poop but no other sign of problems. Could this be cocci? I tried to find Sulmet or Amphrolium but no success other then medicated chick starter. Since bringing them into the house where it stays about 20 degrees, the bloody poop disappeared (within 12 hours), they are all active with no hunching over and are all eating well. Were they just stressed out? Should I order meds online and give it to them anyway? Also, I was looking for new homes for the chicks before this happened but put that on hold until they are symptom free. How long should I wait after they are symptom free? I really don't have the space for these chicks to remain in my house so I need to get them new homes but I don't want to contaminate someone elses flock.
