Help!?! First I would like to thank BYC and everyone here. BYC has been a great resource and I have learned SO MUCH!!! Thank you thank you thank you! I have a small 22 week old flock of six pullets & one cockerel. I have had them since they were 8 weeks old and all have been happy, healthy and have grown faster than I ever imagined! There are Four Silver Laced Wyandottes - Lacey, Daisy, Ash & Roc La Roo, one Black Copper Marans - Dixie, one BCM/Rhode Island Red cross - Lucky. Lucky is fairly aggressive, the largest, smartest, boldest & most definitely Top Hen! & ranks higher than the Roo. Until yesterday I thought for sure she would be the first to lay an egg. These are my first chickens. Yesterday afternoon/evening Lucky started acting very "sleepy". Hanging around foraging & ranging around with the others but very slow and would stop & zone out and close her eyes. This morning our Roo crowed for the first time! (Because Lucky is sick?!) Today she has been mostly following along with the others and going to the coop for frequent naps and still the frequent zoning out/sleepy behavior. I have not noticed any abnormal BMs. She does not seem interested in food or water, even when I bring her scratch which she normally would peck from my hand, HARD. Reading other posts it is possibly Cocci or other worms/parasites? Or maybe she ate something she shouldn't have? There are no mites/lice I have observed. I have thoroughly cleaned/disinfected the feeder & waterer, trekked to Tractor Supply for Wazine & Amprol and have treated water in the coop and Lucky's temporary abode. I do have her separated in a dog crate in the garage now. We are doing the "deep litter" and I just cleaned it out a couple weeks ago but but tomorrow I should maybe thoroughly clean the coop (again! ) ? Only two recent changes... 1. We experienced the recent bizarre "Polar Vortex" with three days of extremely unusual single digit numbers (we are just outside of Atlanta). I put extra pine chips in the enclosed coop/house for warmth & closed it as best as I could. I brought water to the birds 2-3 times a day & kept the food up & gave extra scratch. She does have teeny tiny black dots on the very tips of her comb, ??a touch of frost bite?, all the others seem to be just fine. 2. Yesterday I also changed their food from Nutrena Chick Starter/Grower Medicated Crumbles to the NatureWise Crumbles. I mixed with the remainder of the Starter/Grower, some new Scratch and Oyster Shell. Any thoughts and/or additional advice?? What else can I/should I do?? Thank you!
