I've got a seven year old Barred Rock who about two to three weeks ago began appearing heavily lethargic with pale comb and wattles. Her posture is also drooped, tail down, head tucked, and eyes half-closed. I also often find her laying down or choosing to stay back while the rest of the flock comes over to see me. I first assumed she was starting her molt but it doesn't look like that is the case. I'm fairly certain that she has retired from laying so I can't imagine that this is anything of reproductive concern either. She's always been a healthy bird and her only incident was a run in with bumble foot several weeks ago. I did treat her and from what I can tell, eradicated the infection, but she hasn't stopped limping. Based on general observation her foot appears healthy. No swelling, inflammation, redness, dark spots or reason for alarm. Throughout all of this her appetite has remained normal and no other symptoms have manifested. Is it possible that the lethargy is related to the original bumblefoot? Or is it likely that there is something else going on?
