I've got 12 White Dorkings, 3 EEs, 3 Barred Rocks, and 3 Speckled Sussex on order. I'm trying to figure out a ship date, which all depends on how early in June they can go into the coop. I live close to the seacoast in NH, so day temps are usually 60+ but nights can still get down to 40+. Would the first week of June be OK? they'll be 8 weeks then. They are my first batch of chix so there are no other hens in the coop already. HELP!
