Strange Welsummer Egg

Something a little bit different today, with the arrival of a very unusual looking egg from Matilda the Welsummer.

Matilda is a handsome bird and there really is no doubting her Welsummer status. Welsummers are known for laying decent sized brown eggs that are often speckled. They are certainly not known for laying eggs that are almost white. The egg in question is shown in the image above. It has a small circular patch of normal pigmentation, but is totally white apart from that.

From what I can gather the pigment of a Welsummer egg can be rubbed fairly easily from the surface of the shell. For some reason it appears that the usual pigment wasn't put on the outside of this shell, or it had already been rubbed off somehow before the egg was collected.

I'm sure the taste of the egg will live up to Matilda's normal high standards, but I thought its appearance was notable enough to mention here.

Update (10/2/17): Matilda has just laid her next egg and it has reverted to normal Welsummer speckled brown.
