Can an olive egg laying hen lay a blue one?

[chicaus]

I have an hen that lays Olive green eggs. A Silver laced Wyandotte that lays a cream egg and a blue laced wyandotte freeholder.

They are all 9 mths old.

A few weeks ago I found a blue coloured egg rather than an olive.

Can I safely assume something went wrong with my olive laying hens ink cartridge that day or have I got a mix in my blue wyandotte?

Its winter here in Australia so the SLW has stopped laying. This blue egg appeared in Autumn... just wondering what surprises I have in store for spring if any?

If it only happened once, then Yes.
