Just the usual. Make sure they have food, fresh water, grit, calcium and a dust wallow. Sometimes, they can bully each other; I set up coves made from pallets in my chicken pen for them to duck into to avoid line of sight. If you plan to keep roosters, make sure there is plenty of room for them to roam and around five hens each, else they will tend to fight each other. Use square material for the perches, not round. Much easier for them to grip. I ripped 2x4 studs and sanded them smooth. If you can free range the birds, they really like it. Not only will it reduce your garden of weeds and bugs, but they hens lay better.
