Thank you for your reply,
@TropicalChickies ! Yes, within a month of starting this adventure, we had approx 66 chickens from 3 different sources.

. I lost 8 out of 10 of one group (mostly young lavenders), and I have been dealing with losing a Leghorn pullet here and there after they start becoming lame. Alice is from our original group of six adults and seven 1 or 2-month-olds from a local person. We did lose a young rooster suddenly from this particular group a few months back....prior to the necropsy.
I did start Alice on the Tri-sulpha antibiotic two days ago, but then she seemed so stressed/down while I kept her separated from the flock. (That's why I put ShawShank in with her, but ShawShank really got agitated after a while of being out of her normal surroundings.) I was at a loss... Take a chance that the antibiotics will do the trick, or keep her with the flock so that the stress doesn't kill her. I was hoping that the symptoms I am seeing is due to possibly the start of molt? So, she had only 2 days of antibiotics - that is if she even drank enough to have any benefit. She has eaten some more scrambled eggs today, but she wasn't interested in any meal worms.
I do not see any bugs on her, but we might give everyone a treatment of ivermectin topically tonight. I have to look back at my notes on the schedule since that's one thing I don't see on my calendar.
It's damp and chilly here today, so I left one of the doors closed on the coop to keep it comfy inside. I'm second guessing myself about putting her back with the flock since I obviously cannot monitor her that way.
