Newbie here. I really wanted to purchase older pullets that were coop ready since I have no experience with chicks or indoor space to put them. That is proving to be cost restrictive, though since I want certain breeds and numbers. If I wait until summer, can I brood the chicks outdoors without a heat lamp? By outdoors I mean on my covered patio. I'm looking to get 20-25 chicks. Thanks for your help!
