I didn't know that the bottom of my feeder had some green moldy food that stuck and I think my hens have been affected. They are acting okay, just once in a while they go and sit in the bushes like they are very tired. They will close their eyes and look like they are muttering to themsleves. I want to do a flush, but is blackstap molasses okay to use? Can I also add ACV to the molasses water?
