Loose stool after changing feeds?

[CooksCritters]

I just changed my 8 week old chickens' feed from FRM grower, to Tucker Millings non-gmo starter/grower. I did it fairly gradually, but I've noticed some of my birds have got loose poop. They're still acting as normal as ever. Could the loose stool be from the feed change or something more serious?

It could be either. If they are not listless, just keep an eye on them. If it's hot there, they could just be drinking a lot of water.

We live in the florida panhandle, and it has been terribly hot the last few days. I hadn't even thought about the water drinking. They're all still running around like crazy, but I'm watching them carefully. Thank you!
