Calcium coated egg?

[LiizardWiitch]

I'm pretty new to raising chickens and I'm having a hard time finding exactly what this is but from what I can tell it's a calcium coated egg? This is the second egg I've found like this and at first I thought It was a hole but I'm pretty sure it's just a dark brown spot

Also pretty sure it's from my lavender orpington which started laying a little later than the rest of my pullets
I was already planning on buying flock maintenance feed next round of food instead of layer beacsue I've heard this is much better for them. Do I need to cut back the calcium in the meantime?

It's likely just heavy bloom with some calcium deposits, nothing to worry about especially with new layers.

If the dark spot is just dark color, it is fine.

If the dark spot is actually a hole, it's probably a new-layer glitch, and not something to worry about either.

What do you mean, "cut back the calcium"?

I would recommend that you keep a dish of oyster shell (for calcium) available to them at all time. Do not mix it into the food, just leave it there for them to eat as they wish. Most hens are pretty good about eating the right amount for their needs.

If you are feeding layer feed, they probably do not need to eat much other calcium. If you feed a feed that contains less calcium (like flock maintenance feed), they will need to eat more oyster shell to get the right amount each day. Keeping the oyster shell available separately is usually the easiest way to provide the right amount for each bird.
