Hi all, I've read the site since we got chickens in April of this year. I could use some advice now. I have a pullet (Americauna) about 4 months old now that started falling down the day before yesterday. She will stand kind of hunched, not holding her head up. She is trying to eat and drink, but will loose her balance when walking and just fall to one side. We got her from the local feed store, along with her sisters, 2 other Americaunas and 2 Barred Rocks. They are all acting normal. We also have 4 older birds that came from same feed store (2 Red Stars bought at laying age and 2 Black Austrolorps bought day old) and are eating, laying, acting fine and 4 BLRW's that my daughter received as a present from her Aunt. The Wyandottes are acting pretty normal except for the splash Roo that seems to have un-ending diareaha. His droppings are always runny and yellow, sometimes clearish, for about a few weeks now. I had a bird that was dropping very bloody stools as well. I had treated the entire flock with Corid after having our vet do a fecal test. The results were medium to high level of cocci. This was about 3 or 4 weeks agao. After the Corid treatment, all was fine, except for one bird that showed bloody stool again after 2 weeks or so. I caught her on the roost, so I know it was her, isolated and ran her through another round of Corid (as I didn't want to miss out on eggs again). She cleared up after a week alone and is back with flock. Now this morning, I found a spot of bloody runny stuff in their yard. So I don't know if all this is related or not. It seems like separate problems, but I would really appreciate some help finding answers as I'm certainly new to this and trying to diagnose on my own doesn't seem to be helping. I did think the runny poo from the Roo might be worms, but that didn't show up in the fecal test I had done. I figured if worms were the culprit, it would affect them all and show up in the test. So my action thus far has been to start the whole flock on Zyfend to treat for worms, which I started 3 days ago, and to isolate the Americauna in a seperate small shed I have so she can heal up as I'm hoping it's just a hurt leg. I have feed the flock with DE in the food pretty much since the beginning and use ACV in the water most times as I am striving to treat naturally first. Please let me know what y'all think. And a big THANK YOU!
