As long as they don’t go crossing the road (see my current thread on Around the Farm), freeranging hens are hardly any work at all.
Even when on Lockdown - as my delinquent hens now are - all I do is refill feeder & waterbowl & scoop poop daily.
I use one of the scoops designed for litterboxes & compost the manure & shavings. Great for your garden when done!
Every Spring I completely sweep out the coop, put down Sevin & new shavings.
Put boards under the roosts & scooping manure is even easier.
My coop is a converted garden shed - tall enough for me to stand up in & probably 8’WX10’L.
Former owners kept chickens & turkeys so I benefited from their homemade chickenwire dividers & door to the fenced yard. Nestboxes are fruit crates - 2 for 6 hens, but there’s always a “Best” box & they all want that one.
I added a small screened window for ventilation (reinforced with hardware cloth on the outside) & ran electric for a light, heatlamp for the worst of Winter & a heated waterbowl
I had to refence the yard & made it smaller, but still at least 10X20,
When you fence be sure to bury about a foot of wire - facing out - so varmints cannot dig into the yard.
My yard is roofed with a grid of baling twine - forms a visual barrier so hawks won’t dive in & does not collapse under snowload.
I’ve kept as many as 7 - 6 hens, 1 rooster - & they had plenty room.
I think the Rule is 1 square foot per bird inside the coop.
I started with 5 9wk old pullets.
I added 2 day-old chicks a couple years later & added 2 2-3yo hens after losing the rooster & 2 hens to a passing fox.
They spent the first month in a 10gal aquarium in the coop, then in a sectioned-off part of the coop & at about 3 months they joined the Big Girls.
I probably wouldn’t bother with chicks again - too impatient to wait the 6mos until they start laying.
And one of them was the “Oops” rooster.
The odds of getting a decently-behaved rooster are too low to bother.
Unless you want to hatch your own chicks, don’t.
When my flock was down to one due to illness & predation, I got 6 young hens from an Amish farmer.
They were laying, but just started as they still had baby combs.
From my current 5 I get 3-4 eggs daily - oldest hen is now 6ish & has either stopped laying or does so infrequently.
They are very entertaining & a lot smarter than I imagined.
A lot of personality in 5# of feathers!
