Each pen accommodates a Roo & his hens. I have 10 Roos...10 sections, predator proof & mouse proof 1/2" wire totally enclosed pens. I really don't have a way to run hoses for 10 sprinklers & wouldn't have the water pressure from the well to sustain a steady flow to run through 200 feet of 10 different hoses.
I tried watering myself every night but I really don't have 2 free hours every night to stand there with a hose.
No way to run hose & sprinkers inside pens, I'd have to leave a door open, so with 4 foxes on mouse patrol...yeah, they'd love a chance for chicken dinner. Can't really get rid of foxes, they do a good mouse & rat patrol job, they've been here long before I moved here & when a few were relocated years ago by a neighbor, more just show up...sort of like groundhogs, ya never really get rid of them permanently, more just magically show up. I've actually got a good synergy going with the foxes...they keep my place rodent free. I have a friend with a rat issue 30 miles away...what those rats have done is unbelievable...chewed out walls in their barn! No, my foxes can stay, my chickens are safe.
I'm considering big chunk, natural bark mulch, may give that a shot this time, see how it goes...as far as sod, well it really isn't that bad, it's a good work out for me, I feel like I've worked out afterwards, and I like being active & toned, so it's a good way to not get flabby, Lol. My flock loves it, they hang with me & enjoy the bugs I rake up prepping for the sod. I guess I am a bit of a workaholic, I actually do enjoy projects that most others consider to be work.
