My mix was FBCM and American Game. Maybe is I used a Game roo over a Marans hen I'd get fatter roos. IDK. Lots of people bought hatching eggs and chicks and lots were processed. My Games lay lots of eggs and I'd heard Maranas taste great, but just couldn't bring myself to eat a Marans roo. LOL My husband was supposed to do all the processing, but since he died, I just can't do it like I thought I'd be able to. Maybe I should start with meat birds first since I know they don't do well after a certain age, but I don't know if that would help any. I haven't processed quail since the one time either. I did good and they process fast, but I only have one quail with a name and that we raised like a pet, although she is out with the others.
