In the last rain we had a leak run down the post that the feeder box hangs on! I found this a few days ago when I threw in my egg shells. I pulled most of the mildew out but some sluffed off now I have cleared the whole box and it did run all the way down but just in the back corner. Of 7 birds I don't think they got much if any but now I have a bird that did not feel like free ranging today and just sat by the fence all day. She had clear eyes, red comb and layed an egg later in the day. Checked her wings legs, since she a rather large Brahma, and will jump up to her roost and down (3) feet. But they all look fine except for Haskell. I have noticed that all of them have a florescent blue green poop but that I feel is because of some kale and collards that I fed yesterday. They eat more veggies then mash and do eat quite a bit of scratch (spoiled) kids. I would think that they ate more free ranging the last few days then their mash! Anyone that has had a bird fail because of this I have heard that the symptoms may take awhile to form. Thanks in advance, worried mommie!
