Thanks for the reply. She did not get injured. They are all fenced in and cooped at night. No rooster. Her legs do not appear swollen but the are slightly darker (orange) than her twin sister. She is foraging now but, still has some balance issues and she is not scratching like her sisters.
Its been years since I used this website. I have three chickens now with 10 more on the way. We have the hens for egg production. One of my hens (approx 1 yr old) is walking funny, stumbling, loose stool (this morning when I picked her up) and her comb is pale... I am trying the epsom salt bath...
