What size is your coop / run and how many chickens do you have? The minimum recommended space for coop space is 4sqft per bird, and run is 10 sqft per bird.
Maybe take a look at this link of a search that I've just done - it may give you some inspiration - https://www.backyardchickens.com/search/148415/?q=entertaining+chickens&o=date&c[title_only]=1I have two. The coop is 1m by .7m and .7 high, and set another foot off the ground, and located outside the run - stuck on the side of the run. The run is a chicken wire covered little green house, so maybe 2m by 2m? And walk in height. They have some high roosts and various bits of large driftwood to climb up on to get there, so they can use the height also. I'm pretty sure they have plenty of room. They're just rather be grubbing in the garden on a nice sunny day.

Forgive me if I smile a little here...in Oregon...NW Oregon...where we get LOTS of rain all year long.
They will forage throughout the rain all day long.
You have tough chickens! The run has been open all day but they've just sat inside looking disgusted by the whole deal! They're summer-born chickens NOT liking their first winter....
Well, tell them their Oregon cousins are laughing at them!
(They won't snicker too loud though. When we get our rare snow, my birds stare terrified from the coop until it melts...last winter that took a week! One braver hen tried to "walk" in the drift, sunk, flapped up sqawking loudly, bounced up and down about three times in the snow to face plow into a snow bank where she would have remained huddled until she froze to death had I not stopped laughing long enough to pick her up and put her back in the coop run with the rest of the, uhm, chickens.)
