Hi all. Our flock of 5 are almost 3 yrs old. Laying well, acting chicken normal. They are free range on weekends and after work. Worried. On one, a blister on rt ear lobe x 3 weeks. Also, lobe not smooth, like usual, looks a little lumpy. Other has small scab on rt side of comb, just saw for first time this weekend. Thoughts? TY
