Hi guys...my chicks are now 3.5weeks old and are trying to fly around the room when they are out of the brooder. I have a run and coop basically finished ( will have it all done this weekend) and was thinking of putting them outside next week. They have already been outside a couple of times for and hour or so each time to run around in the run. They are really feathering up pretty nicely and I think given the temp in the brooder is about 70-75 during the day and probably as low as 65 at night that they would be ok outside by now. The temps for next week will be in the low 70s during the day and about 50-60 overnight. I can always put a heat lamp in the coop at night. what do you think?
