I'm new to backyard chickens, but need some help. I have a chicken that is about 2.5 years old and was attacked by a fox (I think) a couple months ago. It had a broken toe (bent backwards), but after a week was keeping up with the rest of the chickens and running around like normal only with a bent toe. After months of her being okay, I noticed her limping today. I looked at her broken toe and it is swollen. I can't find anything online to tell me what is wrong, and I'm worried she is in pain. It is slightly pinkish/purplish and only swollen at the joint where it is bent. Any ideas or suggestions? I really appreciate it!
