Odd texture

[Ozz]

Occasionally, I’ll get an egg like this. I’m feeding a 16% protein Purina food. I have six other hands but only get one of these occasionally it’s usually much larger than the other eggs. Looks like it’s got tunnels under the surface.

Have you ever had respiratory illness within your flock?

What do you feed, including treats?
Do you add supplemental light for winter laying?
