i have 2 golden laced wyandottes, 2 black astrolopes, 1 EE, the other fell to a raccoon. 1 RIR , 1 welsommer and 1 unknown. im on long island, all stand both the summer heat and winter cold just fine. i give them places to hide from the wind in the winter, and shade in the summer. they are starting to get older, so their egg production this winter was pretty spotty, but they did pretty good up til now. just this week i started getting eggs daily, they probably realized that the 8 week old chicks in the next pen could be there replacements so they are laying again. good luck choosing your chicks. i choose a mixed flock and it worked out fine.
