I know I should have checked this out BEFORE I started letting my girls hatch eggs but....I have a Barr Rock Roo and then 6 BR hens, 3 Delaware hens, 5 English Game hens. The banties just hatched out 10 chicks. Some of them are obviously BR, but 3 are from the Delawares I think. I have never seen the roo with the game hens so I am pretty sure the chicks are all foster chicks. Oh Loardy, I need to seperate my flocks.
