So I have a chicken named Roxy. I've had her since a chick and she is now 2 years old. She's a sassy girl but she's my baby nevertheless. A few weeks ago I had noticed 3 of my chickens started getting bumble foot. I believe it's from there nesting boxes being about 5 feet off the ground (which we are now getting fixed). Anyway, We treated all 3 girls by removing the black scad and putting antibiotics on there foot then bandaging them up. Well, one of the girls, Roxy, never healed and her foot has progressively got worse over time. Going to the vet is out of the question because my parents don't want to spend a lot of money on one of my chickens . She has started limping over the past about 2 days now and I know thats not good... What should I do guys ? I love my chickens. Here are some pictures of her foot.
