Pro - Does anyone else's nest boxes get soaked in rain?

[Ella]

Hi guys its Ella here with a rather strange subject. It appears that one of my three chickens Rocky (my German Vowerk bantam hen) has a sort of triangular growth on the back of her leg. At first we thought it was mud, so we tried to wash it but all of the mud came off leaving an inch of hard growthy stuff. I don't really know what it is..or how to get it off of her foot or anything so help would be great!

Do you have any photos? It could be a spur bud.

[Ella]

No I'm afraid I dont and it's very difficult taking pictures of it as she never sits still

Hi Ella, could you take her to the breeder or a farmer for their opinion.

[Ella]

Yes, I think grandad is taking him to Andy, the person that we got her from :3

Let us know what he says
