I agree with ch1ckenmama.
Once they are that old they will be perfectly fine with the crazy temperatures. Here in Arizona, it is in the 90's during the days and goes down to the 50's at night.
Ok. No rush on the pictures. Take as much time as you need:)
If they are that old then they should probably be fine with the temps and weather. When putting them in, just either pick them up and take them out one at a time, or let them jump out of the brooder and into the coop. Hope this helps...
