We have 4 hens that we have had for 3 years. Our most consistent layer has always been our Rhode Island Red. She is also the most friendly and interacts with us. None of our hens have been laying since the weather in Northern NV turned cold which I expected. Now my Americauna is laying but still no eggs from The RIR or my 2 Barred Rocks. For the last week or so, she has not been roosting and today I noticed that she seems a bit listless. I just went out to check on her and she is sleeping in the nesting box but I don't think she is broody. My Americauna has been broody before so I know what that looks like. The crazy thing is she looks better than ever, super shiny and healthy, her comb looks fine. She is eating and drinking although not with as much gusto as usual. Her poop seems to smell worse than normal chicken poop. There was a little poop stuck on her butt feathers but not packed on. She's just not right and I don't know where to begin trying to diagnose what could be wrong. Any thoughts?
