Bumpy first egg

[Jen81]

We have a new egg today. We have been waiting to see what colour egg she lays…
This being her first egg should I be concerned with the amount of calcium build up on the shell? All hens are on the same diet and no issues with their shells.

Well, I would be watchful but hope it's just a new layer glitch and things will smooth out.
Not much you can do about it anyway.

But.....What all and how exactly are you feeding?

Hopefully it sorts itself out. Feed wise, premium 17% protein grain with no grind crumble, mixed with some whole grain scratch mix. I give this to them straight and also ferment it. Plus daily kitchen fruit, veg scraps. And they free range after their morning kitchen feed.

What are the brands and model of these.
The kitchen feed might be lowering their overall nutrition.

I'll link to the Egg Quality Guide about sandpaper shells.

https://www.thepoultrysite.com/publications/egg-quality-handbook/17/sandpaper-or-rough-shells

That guide is written from a commercial standpoint, not for our backyard flocks, so don't read too much into it.

The egg laying process is fairly complicated. It is fairly common that it takes a few days for some pullets to get all the kinks out of their system when they first start. To me it is somewhat surprising that so many pullets get that process perfect from the start. Since that is her first egg I would not be worried at all.

To me it looks like her shell gland is not working properly. There is a reasonable chance that will straighten itself out in the nest week or two. Even if it doesn't, the eggs will be OK to use. There is nothing wrong with them from a nutritional or safety standpoint. The shell is just a little rough.

The commercial hens lay eggs like ours, some with defects. The difference is that the commercial eggs are sorted so we only see the perfect ones. They sell their imperfect ones to places like bakeries or pet food manufacturers that open the eggs before they are used. Those eggs are perfectly safe, just not perfect as far as appearance.
