Soooo, I scoop multiple times a day, too. I use a dustpan and a trowel left over from when we built our barndominium, not only in their runs but around their 2K square-foot yard. Keeping their ground clean is my Zen, like Luanne's swimming pool in
King of the Hill.
Where did you get sand quotes from? Local quarries or landscaping companies? That's great about your hen being on the mend again! It'd be interesting to hear if sand helps her big foot. At the very least, the drainage should be an upgrade during the wet season.
On the roundworms: I haven't actually seen a worm in poop. Yay because ick, but it is a little confusing. We got the diagnosis both times via poop analysis at a vet's. It wasn't a surprise. They eat lots of creatures from the dirt. In both instances, the vet provided 2 doses of Panacur for their water to be administered 10 days apart. In the 2nd instance, that treatment evidently saved the Langshan (she finally turned around 12 hours after taking in a good dose). Not seeing the worms is confusing. It's possible they weren't the visible kind...I'm just not sure, and like you am doubtful those jokers were eradicated. Or that they'll ever be fully gone.
Going forward, I've been considering starting with quarterly testing, and if they keep coming up positive, I may jump to quarterly worming, rotating treatments to reduce resistance. We generally take a biodynamic approach, which in this case would translate to prophylactic remedies (like garlic and pumpkin seeds) instead of chemical wormers until they achieve balance with the worms or die...but our flock is small and treasured. I'd rather medicate than stick to those principals in this case.
According to the forecast, it looks like the reports of "a repeat of 1993" were clickbait

Should be rain here, too. Is your region de-iced? I'm betting your winter temps are cooler than ours. It's been 50s here but some roads are still closed: the rugged mountain "roads" a few wicked GPS devices send tourists down. For some reason, instead of taking 30 seconds to find any of the abundant alternate routes to Gatlinburg, people
drove around cones and slid off the road. We're talking 60+ cars in creeks, down mountains, stranded on Christmas...we needed signs that said, "Hey, if locals say the road is bad, believe that." Because the locals are like mountain goats in cars. They never close roads.
On our end, we miraculously didn't lose power, and all the animals had a good time--even our bees were flying yesterday--so we'll count it as an amazing holiday despite being away from the family and friends we usually spend it with. Photos for kicks. I'll miss sledding down to the chicken yard every morning, ha.
