Hi all, I have two egg-laying problems.
The first one is that I think I have an egg-eater? Today was the second day in a row that I've found a brown egg with a hole in it like so:

Its only been one brown egg each time I've found eggs broken like this and with the contents spilled in the nest box. Is this what egg eating looks like?
As a result of the first time having found an egg like this I added another nest box cause I thought (and hoped) it had been a crowding issue... I really don't want to deal with egg-eating.
The second problem is that one (and only one) of my chickens, an Easter Egger has been regularly laying eggs like this:


Are these simply calcium deposits? She's been laying eggs like this daily. I'm not sure which hen it is, but I have two EEs that lay blue eggs, one is almost three years old and the other isn't even one.
Are these bumps a problem and if yes how do I stop them?
Thank you!!!
