My 1 year old hen started growing this little lump on the side of one toe two days ago and I've been watching her walk and it has grown in size. It isn't making her limp and when I catch her and touch her toe, she doesn't seem to flinch as though it is painful. The lump itself is very hard, white, no warm (as though it is infection - but perhaps it still is infected?). I am going to try to soak it in salt water if she'll allow it. Should I worry? What should I do?
