Before & 3 weeks old!!

Not sure where you are located, but in August here in SE Texas chicks do not need six weeks of artificial heat as it’s warmer outside than it is inside the air conditioned house where we brood new chicks.
Our most recent batch of 24 chicks hatched on July 22, were completely off of artificial heat by they time they were two weeks old, and were moved outside at 3 weeks old into the 3’x12’ transition pen located inside the big run to start their transition into the “real world”. During the daytime while the older chickens are out free-ranging, we let the babies have access to the entire 8’x24’ run, then herd them back in their transition pen about an hour or two before the older chickens come back in for the night.
Chicks grow fast, I’d really recommend not waiting any longer before putting your builder “to task”, and hopefully he doesn’t have other commitments that will delay the start of your build.

Hi, I'm in England & the British weather isn't the most reliable, last month the temp was in its 30s & its now dropped to below the 20s, centigrade that is, & the rain of late has put everything on a stand still.

Mine are the same age & I just moved them into a large pen in the garage with bird netting attached to the ceiling (only cost $15 for the upgrade). They love perching at different heights & dust bathing at this age & need lots of room to run around & explore. The change in their behavior was dramatic once they had height & space to jump/fly. They are so happy & playful now! Just get some chicken wire & make something temporary to buy some time while you finish the permanent coop.View attachment 2302661

I love that!! It's like a chick adventure playground!!
