Straw or woodshavings might be a better option for inside the coop, if that's what you meant by the hay. otherwise, looks like you've got it all sorted! Happy chicken keeping! Oh, and just to add, if you are planning to have a run and then let the hens out in the yard (I don't know if this is common or not) but my girls just shout at the gate to be let out even if their run is much more exciting! Maybe my hens are just strange...
