Brooder to coop questions summer in FL

Looking for some suggestions/thoughts. My wife got four chicks and we've been following the heat schedule (95, 90, 85, 80; weeks 1-4). We're now in the latter half of week four and I'm a little puzzled how to transition them to the coop in the FL summer heat (week 6ish). It's been low to mid 90's but heat index is upper 90's, so not sure right way to do this especially if they need to be kept in the coop for a few weeks before being let out into the run. Should we keep them at 80 for the next three weeks in brooder inside and then throw them suddenly in 90-95+ heat outside or is there a better way to transition them? We took them outside for the first time this week and they were all panting and sprawling their wings out, so we got nervous and brought them back in. That reaction is what made us unsure how to transition them. Tried it a second time, later in afternoon and in the shade and they ran around normal. Any thoughts about best way to transition to coop in two weeks given the heat?

At 4 weeks, my birds here in Southern Oregon are out in the grow-out pen this time of year. I think your birds would be fine to go right outside. I myself don't see the point of confining chicks to the coop if you have a secure run. If you plan to free range, I can see confining them for a short period to teach them where to sleep, but if you have a run, let them access it. I don't do gradual transitions much, I just move them where I need them, and my birds all do fine.

Those heat schedules are guidelines, not hard and fast rules. It's also supposed to be an area they have access to, not the temp of their entire enclosure. It's meant more for early spring, or birds that are brooded outdoors. Just go ahead and put them in the coop now, have plenty of shade and water. They're going to pant and spread their wings out, that's what birds do when they get hot. In your area, they're going to get hot, not much you can do about that. Shade, water, a good place to dust bathe to get to the cool earth--those are nature's ways of cooling off.
