I bought a few americana chicks from a local chicken farmer that own a quite large chicken breeding facility that contracts out eggs and birds to his clients... pretty legit... they are certified and livensed for everything... Questions is... he said these americanas i have, have been bred for generations to only lay good blue eggs... not to say i wont ever get a green egg, but he said they should be far and few between... We will find out when they got old enough to lay... but question is - is this the type americana i would want to cross with a copper maran to try to get olive eggers?? Or do i need a green egg laying americana to cross? Second question... how do you go about darkening that olive egg? Cross the oliver with the maran? Third question: once i get an oliver layong the olive color i want... just only breed those olivers from then on?
