Weird hole

[Jose-hen-phine]

Hi all. One of my girls started laying eggs with a weird hole. At first I thought my Broody hen made it when she took it to sit on. Today I inspected one of the eggs and the shell doesn’t look like it’s been broken but more eroded. Any ideas or suggestions? I’m stumped. They free range, get meal worms, black oil seeds.

It looks like someone stepped on it and put a claw mark in it. I have that happen from time to time. I can't speak to all those scratches on it ("erosion") though.

An calcium deposit must have flaked off, and the lines are normal. :]
