I am trying to pick my chicks for delivery sometime in April. I am definitely getting 2 buff orpingtons, but other than that I cannot decide. I love silver laced wyandottes, but I have read many mixed reviews about their personality. I also can't decide on either a speckled sussex or rhode island red. I live in the city and can therefore only have "5 egg laying birds". I Live in KY, so colder winters and some hot summers. I was thinking I might choose 1 barred rock, 1 silver laced wyandotte, and 1 of either SS or RIR to go along with my BOs. Can I even have such a mixed flock? Please help me choose my chicks and tell me if such a mixed flock would be ok!
