Our Cream Legbar hens, Arwen and Annie, lay us some lovely sized blue and olive eggs. Annie seems to run around like a busibody annoucing everyone's eggs, whilst Arwen is much more sedate and actually had the top hen spot for a while. Our girls aren't the best examples of the breed but I love the litte crests on top of thier heads, together with the floppy comb it looks like a fancy hair do.
The Cream Legbar is as a British rare breed and you can find out more about them on the Rare Breeds Survival Trust website. They nearly died out in the 1970's as there was little demand for thier eggs, which come in lovely shades of blue, green and olive. Thankfully they are making a bit of a comeback, I even saw a boxes of Cream Legbar eggs for sale at our local Tesco the last time I went in, although they were the most expensive eggs in the shop. The eggs get thier disintive colour from thier Araucanas heritage. These birds actually have an alteration in their DNA which causes the egg shell to be blue. If you want to read more about it there's a great article here, although it is a bit technical in places.
