@casportpony symptoms lay/flop under lamp or near the edges of the light several even with wings out. They will still drink but are very weak. Had the one poop white and liquid poop on me, and one now has a weak leg. Most just did the weak flop and were dead within hours. The rest would look fine, when I went back the weak ones would be dead, and the next ones flopping. Here is a pick of one of the girls (yes, messy buggers, she flopped by the food which they dug out and made a mess of in just a couple hours). BTW the way my brooder are have worked fine for three groups prior to this, but these were shipped
