First Green/Blue Egg!

We bought 10 new chickens about a month ago (as well as the 6 we got a year ago). The type we got were rare ones from France that naturally lay bluey-green (a bit like duck eggs) or peachy-red eggs. Because they are still babies, most of them arent laying yet, but we got our first bluey-green one today! Good girl Lottie!
I have enhanced it slightly to bring out the green because of the poor lighting, but they are genuinely that colour.
