Here's the solution, at least it's what I've done. Hatch or buy day old chicks. You can make an easy brooder out of a Rubbermaid tub. If you only want a few birds that gives you about four weeks to finish your coop.
You can't put it off because those little peeps are turning into chickens. Chicken math 101!
I'm actually leaning towards doing the fake mother hen thing. I have 5 dogs right now, so having little peeps in my house is NOT my idea of a good time! LOL
