Egg with a hole?

[MadelineintheMountains]

Hello!

My 3 year old Easter Egger laid this egg. I can't tell if it came out like that or if another chicken pecked it. But the other eggs in the same box all were untouched so that seems unlikely. No yolk in the nesting box or in the egg. There seems to still be some egg white in the shell. She has a history of weak egg shells but has been doing better this year. Her comb is looking a little pale today, we had extreme heat yesterday, and we lost one of her sisters this week. We give them oyster shells so I'm not sure if there's something better for calcium for them if that's the problem.

Let me know your thoughts! TIA

It has obviously been dropped/bumped/pecked/whacked. The shell may be extra brittle or maybe not, but those ragged, cracked edges with broken shell inside the egg say force was applied from the outside in.
