I think my oldest chicks will be ready to go out to their coop by the time we are finished with the renovation and run. We are not having electric in the coop, so no way to do a heater (I have an Ecoglow). I started thinking today that *maybe* I could have everyone outside during the day, and then bring the three youngest ones in overnight to sleep in the brooder, leaving the big girls to sleep in the coop. I think the days are warm enough for the youngest ones now, it is routinely reaching mid to upper 70's and higher. I don't like the idea of separating them until the youngest can sleep in the coop because I worry about integration issues. Does anyone think my plan would work? Or would there still be integration issues, every day, because I'd be removing the youngest chicks in the evening and putting them back out in the morning? I don't want to leave everyone in the brooder until they are all old enough for the coop because the brooder is big, but I think will be too small to house everyone comfortably until then. I only designed it for 7 chicks and now I have 10...go figure Thx!
