Hi, I have a small backyard flock of 6 healthy 18 weekolds and 2 1 year olds. My friend went on vacation and is boarding her 2 2 year old hens with me (ee and sebright). I put them in their own isolated run/coop. The EE has developed cocci symptoms after 10 days here. The other one is looking perfectly fine, so I strung up some flexible plastic netting between the two of them (now each has about 20 sqft). I don't really have any other predator proof enclosures to fully separate the sick EE. I am going to the feed store to look for corid today, but I can't do that until the afternoon -- the bloody poop symptoms started yesterday. Do you think the EE picked the cocci up from my dirt/large population of wild birds? Is it likely the other guest hen will come down with it? My birds all seem fine at this point, but then I read that they probably have an immunity to my local strain of it from being raised from chicks here. any other ideas on what I can do? thanks.
