One of my 2 yr old RIRs Lovely was lethargic when I went to tuck the girls in for the night. I have brought her into the house with food and water. A friend suggested it could be respiratory or a spider bite.She is also curling up her right toes/legs. None of the other girls seems to be having these problems. At this point I have done all that I can think of to help her and protect the rest of the flock. Any other ideas suggestions? Also paryers for my Lovely that she will soon be able to rejoin the rest of the flock.
