Question about feeding dried egg shells

[Charisse66]

My chickens are 19/20 weeks old and one of my hens started laying yesterday yay!! So I have oyster shell supplement separate and they pick at it a bit so I started drying and crushing egg shells for them- man do they love them. My question is: should I be careful on how much I give them? I read too much can hurt them. BTW my sex link hen started laying after giving this, maybe a coincidence. Help, I don’t want to hurt my babies

Mine prefer flakes oyster shell, itight be Wirth a shot.
Their own egg shells won't hurt them unless they get an impaction, so I'd definitely limit their access.

I'd keep an eye on consumption but generally chickens shouldn't go to town on eggshells, though they do need to consume more eggshell in volume vs oyster shell to get the same amount of calcium.

As some hens don't care for oyster shell as much I offer both mixed together and just let them pick what they want.
