Mildred, my terribly patient Khaki Campbell, who has been plagued with Bumble foot for the last month is starting to show something odd. Her flight feathers at the tips of her wings are bleaching out. They have turned from dark brown to a very light tan in the last week. She had always had lighter feathers there, but this is a dramatic difference. She's been on baytril for the last two weeks for the bumblefoot (which continues to persist and the antibiotics are almost gone - although there is much less swelling and just a pink prick of the scab left). I am wondering if the antibiotics could have caused the feathers to fade or what else could cause sure a thing? She doesn't appear to be losing any feathers or molting. Just the change in color. We have had three days of sun for the first time in months, but this has happened very quickly. She is very active, eating,drinking, laying eggs, and seemingly acting normal.
