Hey all- I have hatched some chicks from a cross of Bantam Barnevelder Roo over Blue & Lavender Ameraucana hens. Could my layers produce olive eggs? The barnie eggs are darker than average but not like a Marans. The chicks are beautiful and have muffs...blue, black, and the others are dark brown and black like barnevelder chicks. I have pure bantam barnie chicks and there are some pretty distinct markings to tell them apart aside from the muffs on the ameraucanas. I wasn't really trying for olive eggers, just wanted to hatch some non-shipped eggs for a change!!
