This picture is from this morning, I had not seen the lump on previous pictures.
Tumor? Wounded?

tumor. looks gross, she probably doesn't notice it.

I always wonder if it messes up the meat, probably not but it is gross.

I have seen those before. Not sure what it is but I have seen them go away as quick as they appear. Mostly see it in summer time though.

At least your tank has water.

And it’s pretty and clean not a mud hole

Water is mostly from a solar powered well. Was almost dry a couple months ago when the pump was out of service.
It’s not my property, belongs to a friend. A good friend. He installs solar- wells, power for houses….whatta ya need?

I think you might get a call from Bruce Jenner. Think he is missing one of those...
