I am trying to figure out when to order my first batch of chicks. I live in Zone 8 and we usually get our last freeze no later than the end of March. I was thinking of getting my chicks in April, but we still might have some cool days. I do not have electricity out where the chicken coop will be (but I do have water!) so I can't put up a brooder. Should I wait until the end of April to make sure it is good and warm??
