I have tried a few things and the heated bowl didn't work so well for me because they kept getting the whole thing filled up with wood shavings, this year i'm going to give this a try https://www.backyardchickens.com/a/wichita-cabin-coop (it's towards the bottom) I thought this was a perfect idea!
I also found this design but I can't remember where the link is!

I was looking at getting on like Aoxa put on but I was looking at the reviews and none of them are good.
