I am setting up the brooders outside, sheltered. It is Texas and the high is 77, very sunny.
Can they go outside now?
They will be fine outside if you can provide them a light/heat at night for those colder nights.
Our lows have been in the 40s, but come Monday, my new kids (2 weeks old next week) are getting the boot to the patio as the night time temps will be in the upper 50s and 60s starting next week. The've been spending a bunch of time outside when it is 60's and sunny and spent most of today out there.
