New to guinea olive eggers and black jersey giants

[Mmmk2020]

There was a woman on BYC who had an accidental guin-hen. It had the size of a guinea but the heart lungs of a smaller chicken. Sadly it died young.

That's what I've heard about the cross breeds, but supposedly they're 2nd or 3rd gen? We have no idea. We're new and I'm sure we more than appeared that way when we got them lol! I really do think they are just straight up pearl grey guineas, which is fine with us
