Hi, I'm a new member of BYC and new to chickens too and am already addicted. I have 5 backyard well-loved girls. 3 - 2 year old Lorps and 2 - 1 year old Americaunas. One of my Lorps is not feeling well. First noticed lots of poop stuck to her fluff fethers about 6 weeks ago. She was still laying at that point but isn't anymore. I've dusted her with Sevin5 a couple of times, cleaned the coop, washed her bum nightly, and trimmed off the fluff feathers. Overall her feathers look dull. She's now pretty lethargic, off her feed, and am noticing a more mucousy discharge from her vent. Earlier in the week, her poop looked better, less urates, and no obvious signs of worms. I've been giving them some yoghurt mixed with cooked grain plus probiotics in addition to their organic feed an all the veggies they want to eat. I hope I'm missing something simple because I really don't like the look of her today. Thanks for any guidance you can provide. Warmly.
