Weird bump on Eggs

[BawkinOnTheBench]

For the last 3 days, one of my white Lethorns has been having something unusual with her eggs. On the side of the egg, there's a slightly raised bump. It's about the size of a dime, and it's slightly gray instead of being pure white like the rest of the egg. It's not hugely raised but you can easily see and feel it. One of the eggs like this also had a hole right there - the center of the bump had fallen in. I cracked that egg and it looked totally normal. This hen has been laying since last October.

Any idea what this is or what causes it? The girls are on layer pellets, they have oyster shell and they get Avia 2000 Charge vitamins in their water at least once a week.

It's probably just rough calcium deposits. I don't think you should worry.

I agree with Jody. Probably just calcium deposits. Here's a good reference page on egg defects/differences:

I thought calcioum deposits just looked and felt like sandpaper? I'm familiar with that; this is different. I couldn't find anything in that egg guide that looked like what I'm describing. Maybe a body check - but it doesn't look much like their picture.

The egg yesterday was normal - so maybe it's going away.

Do you have the egg so you can post a picture?

OK, here's a pic. The intact egg is hard to see - but just like the one with the hole, there's a gray spot on that side of the egg and the shell is thin and weak at ONLY that point. I've eaten 2 of them and they are otherwise OK.

I would say just a kink in the egg laying dept. I have a hen that will lay an egg like that on occasion, only the soft spot/raised bump is on the end of the egg.
If it doesn't continue or only happens infrequently I wouldn't be too worried.

Well, it's been happening almost every day now, since I started this post. During this time this hen has had 1 normal egg and 1 skipped day, and every other egg has this flaw. 3 of them have actually broken - luckily they don't break all the way through, just the weak spot in the center has fallen in, like the right egg in the pic. Even the eggs that are intact I haven't been selling, just because they don't look quite right, so I just keep them for family use.

I have a hen who lays the worst eggs ever. I don't even eat them. They have numerous bumps and lumps and weak spots which seem to change location every so often. The yolks and whites are one big runny mess. They would never hatch. I call them DDT eggs. Other than that, she's healthy.
