I am not sure how to identify bumblefoot infection Therese
on Bumblefoot Infection
Bumblefoot is a general term for any inflammatory or degenerative condition of the avian foot. The condition varies from mild to severe. Looking at the bottom of the foot, you may see mild redness or swelling to deep open abscess. It is prevented by using proper perches (never use the sand paper perch covers as this can cause abrasion), good sanitation of facilities, and proper nutrition.
When a bird favors a foot and sits around on one foot, holding the other up, take a look at the foot. Is it red and swollen or do you see an open sore? If it is just red and swollen, immediately drop dietary protein and feed lots of greens and even the next day, if that is the cause, on a low protein diet and the bird will stand normally on two feet and the redness and swelling will be gone.
If you see an open sore, dip the foot a couple of times a day in an iodine solution until healed. In canaries, bacteria such as Staphlococcus and Klebsiella may result in a deep abscess. Oral antibiotics or antibiotic ointments are not effective for bacterial infection in the foot but the iodine dip will get rid of the problem.
