Well for me, every morning I go and top up the food, cleaning the feeder when its looking grubby, and I bring in the water, clean, and give clean water. Run hands along undersides of perches for any sign of mites, have a sniff about, then I put the kettle on and have my own breakfast.
Then I get them some greens and make sure everyone is okay (are the alert? no one been hurt? are they bright eyed and attentive?), and take the poo out of the house. I can't face that before breakfast

If there are any obvious poos about the place or remnants of previous greens that'll get picked up. I'll also make sure there's nothing untowards happening - no sign of mites in the house, etc.
Another check, maybe collecting any eggs laid already, before I go to work.
Home again later, have a look for more eggs and give them a treat of some sort - usually a handfull of grain to go with layers pellets they have access to all the time, and at the moment they're getting the tomatoes from plants in the garden and the odd scraps (plain boiled rice if its spare, cooked spuds, crusts of our own wholegrain bread once in a while). Don't stuff them with scraps, but the odd treat I think is okay.
Every week or so I brush out the run, getting rid of any pooey bits that are a problem. Also once a week brush all the woodshavings out, remove the newspaper lining, clean as necessary, have a good close inspection for beasties, and replace - adding mite powder just in case.
When it needs it I turn the ground over in the run - at this point I skim off top layer (especially in the un-covered bit that gets wet) and cover with a couple of buckets of compost out of the bottom of the compost heap. They love this - its very well rotted down, I use vermiculture to get a good, rich compost that they love scratting about in. The top layer (now rich in chicken dropping mixed in) now goes into a bucket for another rot down on the allotment with the chicken poo, becoming the most wonderful stuff to mix in with potting compost for tomatoes, aubergines, chillis etc. and just to spread about the runner beans and spuds.
I try to spend 'quality time' with the hens a couple of times a week. I might take a cuppa into the run and sit with them with some treats, allowing each to hop on to my arm (easy to train a goldline into this, takes rather longer with a leghorn...) for a closer look. Look at their vents, look under the wings, make sure everyone is happy, see that they're all reacting well. Or we'll give them an hour or two run of the garden (longer when there aren't tomato crops for them to binge on!) and give them ample chance to sit on our laps for a check over.
I think the thing to remember is that they don't really want to be stressed about this any more than we do. You want to create an interesting environment for them, give them a chance to explore and look about, with different places to perch, things to do, etc. but you also don't want to make it any more work than you need to. You'll soon find a balance.
