I have 2 or 3 hatchery Light Brahmas that are sleeping all the time. Like all day. No runny nose, sneezing, coughing. Butts are clean. Crop empty. Probably just eating and drinking enough. Found round worms in a pile of poo a few weeks back. Been around 2 weeks or so since I dewormed them with Valbazen. Always did have 2 or 3 girls with mush eggs. Seemed to straighten out. But still get one every once in awhile. Might be coming from these. Maybe just something genetically wrong with a few of them. Dang hatchery birds. Any input would be worth looking into. Thanks!!
