Laying down a lot

[robinef]

Good morning! I have two (I think cockerels) who we will actually be rehoming tomorrow. Nonetheless, I still love them and want them healthy. The one who is not yet crowing (but most think it's a roo) has started laying down a lot. I noticed it must more yesterday (we live in southwest fl and it was INCREDIBLY hot yesterday) so I didn't think too much of it. But first thing this morning when I let them out of the coop, it came down the ladder but then a few minutes later just laid down again. It's not terribly warm at the moment, low 80s? We're thinking they're about 3 months old. Any input?

And they always have plenty of shade (their coop and run is partially shaded by a tree and our shed) with a full water bottle before we leave for the day.

I have a hen that always does thet when I see her, I sometimes give her sugar water and she gets up after a few hours but lays again she's healthy and perches but she acts strange these days
