Constant Cracked Eggs

[Ol Grey Mare]

It is worth at least adding supplemental calcium to see if that helps. If it does not you may have a bird with a bit of a glitch in the system which prevents the formation of a really nice shell. Not necessarily detrimental, it just might mean you need to adjust how you manage your eggs and nest boxes to try to accommodate and avoid breakage of her perpetually fragile shells

All flock and layer are separate types of feed, layer feed has extra calcium added for laying hens while all flock does not. You can feed all flock to laying hens, but they absolutely must have access to oyster shell on the side (actually a good idea whatever you feed) and they must have access to grit on the side no matter what you feed

Thank you!
