Four days ago I noticed one of my two leghorns limping some. I did not check her simply because she's flighty, the temps were in the teens, and because she was still eating and acting otherwise normal. Then, by evening I realized that she had not laid her daily egg. The next day I was sure to take note of her behavior. She was still slightly limping and still no egg. But, she was acting even more "normal" so I thought perhaps it was just some fluke that was working itself out. Day three she didn't seem to be limping hardly at all and laid her egg. I was sure all was well. Now today, limping again and no egg. She still came running for feeding time and was acting okay, but I decided to bring her in, bathe her and check her feet. Upon searching the net on Bumblefoot, I realized that my little hen may be struggling with the beginning stages of it....I found a small sore that was black. The sore itself is not very swollen, if at all. I have soaked her feet in an Epsom salt bath and scraped the scab off checking for a "kernel" to remove. I haven't found one, but have treated her foot with triple anitibiotic ointment. I have set her up in a cozy box with bedding for the night. Have I done well? Any other suggestions?
