I used a dark egg gened bcm roo over blue ameraucana hens. I get dark olive eggs from the f1's this way and I don't have to do any more crossing for better egg color unless I want to. I did recently do an experiment with crossing some back to male OE's and some back to that dark egg gened bcm roo. The peacombed girls from that experiment should start laying any day now so will see what comes of those double bcm crossed OE's soon.
ETA: Here is a pic of an olive egg from bcm x ameraucana cross. The olive is 'painted on' kinda like the bcm egg coloring. There is a brown layer underneath the olive...kinda cool! Some eggs look green with brown speckles from the underneath brown color.
A wierd thing from my bcm roo x blue ameraucana hen crossings is that every chick I've hatched (over 35 so far) have been black or black coppered colored..NO BLUES and No dark blues. Wonder what happened to 50% blue %50% black? Very strange.
