Americauna egg color

[maneryder]

My Americauna hen normally lays a pale blue/greenish egg, but recently the eggs are almost white in color. Wondering why the change in color? I have 5 hens, 1 rooster, and all were on a round of antibiotics about 3 weeks ago. Didn't know if it had something to do with that? Or is there something missing from her diet? She is on a layer feed, and is also free range. Thoughts?

egg color will lighten as you progress through laying season. when she takes a break for moulting or winter they will return to darker color.

nicarbazin can cause a decease in egg color.

I wrote the article. I need to go to the university library and get a few more papers to analyze so the paper needs some additional documentation and the addition of more information.
