They just need food (layers mash/pellets if they are laying), water, corn for a treat, grit for digestion and they'll be pretty happy. They do like a perch to roost on at night and somewhere to shelter in the day from sun/rain and a nice bit of earth to have a dust bath in! We've got 4 bantams, Gertie, Silvie, Ginger and Lulu, that keep us supplied with lovely eggs for breakfast!
Congratulations! We've got a couple of chooks too - Baba and Maya (named by toddlers).
They love tinned sweetcorn and I often give them our leftovers from the night before as an afternoon treat. They particularly love veggie scraps, rice and pasta. I never give them meat or dairy though.
Dig the soil compacted in their run in the heat dust mites and flies with the help of a cat chasing up and down outside the wire, they will enjoy whipping out worms from under your fork spikes. Rather the same as gardening cats who like to eat grass while it is cut with shears ! Do not wear sandals.
