Chicks

I seldom make comments in this group, but curious. I bought Several female "True Blues" from McMurray Hactchery 8 months ago. They lay beautiful Blue eggs however two of my True Blue hens are laying a cream color and another one is laying a very dark brown. Now that leaves me with 9 True Blues that are True Blues. I also have two beautiful True Blue Roosters.
I've ordered a few of " True Green" chicks at the end of this month. HAS ANYONE HAD THIS BREED AND IF SO WHAT IS YOUR EXPERIENCE WITH THEM.
