I got a hen from auction yesterday. She was labeled with a bad leg. I felt bad so I bid on her. ($2.50) for a beautiful hen! She is completely black! Almost black comb and waddles....anyway, once I got her home I checked her out. She has a small bump on the pad of her foot. I was thinking bumble foot, but it's not hard, nor is there a scab or any sign of a cut or anything on the foot....she walks, but with a limp. I'm keeping her in a dog crate so the foot stays clean. I've been putting bag balm on it to hopefully soften anything that could be a scab. But i don't know what it is or what to do. Any input would be greatly appreciated.
