I'm hoping that you all can help me figure this one out! I just went out to the coop this morning and one of my 3-yr-old Buff Orpingtons, PomPom, sitting near the waterer that the girls share. I tried to get her up but she didn't really respond other than to look at me. Her eyes weren't bright and alert like they typically are, but they were still open and she was still breathing. I moved her over to a drier spot and when I came back to check on her about 20 minutes later, she was dead. My kids had checked on the chix yesterday and all seemed well, according to them (they usually run to tell me if one of the hens is acting funny). Something similar happened to one of our other Buff Orps about 3 weeks ago. On Friday, Bernie looked a little sleepy but was still moving around, but then when I checked on her the next day, she was dead. Nothing has really changed about their diet or living conditions, other than that it is finally getting warm (ie, above freezing) here in Maine. Why might they be dying all of the sudden? I cleaned out their coop right after Bernie passed just in case there was something nasty in there that did her in... My only thought is that my kids have been in charge of refilling the girls food and water lately and may have forgotten to add the vinegar to the water? Any thoughts or ideas would be greatly appreciated! Especially since we have 6 new babies who will be joining our current 4 as soon as they are big enough... Thanks!
