BackYard Chickens

What types of feeder and waterer are best? Those that sit on the ground or those that hang? I don’t want them kicking stuff into them on the ground like they do in the brooder but maybe that’s not a big issue outside where there aren’t shavings to kick into it? I assume feed and water stay outside in the pen rather than in the coop. True? Right now, the area the pen encloses is grassy. Will it eventually become just dirt? If/when that happens do I need to put straw or something down or...

What was the worse type of breeds you've dealt with as far as them being aggressive and what breeds were the nicest and easy to handle?

The chickens are three months old now and still on Nutrena Chick starter. Please guide us to the best feed going forward. Up to this point I have given them no treats, extra food, anything but feed and baby chick grit. By the way, they are wonderful, happy chickens! Thanks.
