Flock with Diarrhea

[Winchikn]

I'm new to online forums and don't know how to link to my older thread, but my hen who I thought had a partially impacted crop went on to develop diarrhea and pale combs and wattles following a molt. I had a fecal float done and it showed one worm egg but not enough to give the vet cause for concern. I also found one round worm in a poop about 10 days ago (not sure which hen it was from).

Since then, 2-4 others in my flock of ten have developed very watery poo - enough that the back wall of the coop, which I scrubbed to a shine about a month ago, has several smears of runny poop each morning and sometimes there's a few splats on the roost as well. Several of the hens with the digestive upset are in the midst of their first hard molts at about 15 mos but one is a 8 month old Buff Orpington who also appears to be losing some feathers. All are behaving normally, eating, drinking and foraging with the flock - several have pale combs and wattles and the one I'm most worried about actually looks a little sunken around her eyes - I'm assuming possible dehydration. I have noticed what I think are more cecal-looking poops around the run and some appear a bit foamy (pics below).

My flock is ten in total and the hens having issues are mostly the older Caramel Queens plus the one younger Buff Orp. They have access to an approx 10x20 run plus an approx 25x30 orchard and I also let them into my veggie garden today. IE - they have lots of room. I'm feeding an 18% crumble right now because of the molt and they have access to fresh water supplemented every couple of days with ACV. I've also been giving a couple of the hens who are molting really hard a bit of scrambled egg every few days, and they all get a bit of scratch in the afternoon.

A few poo pics below. I've never wormed my flock and am wondering if that's indicated by symptoms?

I would treat for worms if you actually found one in the poop. If I remember correctly, the foamy poop can be a symptom of worms as well.
Hopefully someone with more knowledge will chime in.

I'm very tempted to go ahead and treat for roundworm given some indication for worms and no other obvious issues.

Looking for advice on best wormer to use for a flock that is 3/4 in molt ... in Canada (I'm not sure if the same meds are available here).

I need further advice here. I talked to my vet today about deworming meds after feeling like my flock isn't really improving and the vet said that the egg that was seen in my hen's fecal test a couple of weeks ago was a coccidia egg - but just one so not enough to give them concern.

So we've got that, plus one roundworm in a poop 2-3 weeks back, plus several flock members with watery droppings, more cecal droppings than normal (some foamy), and 4 hens with pale, dry combs, and what I'd say is a bit of a sunken look around the eyes. All are fairly active though we got our first big load of snow here today so they were sticking close to the coop.

I feel like I need to do something given limited clinical improvement, but am not sure if symptoms indicate treatment for coccidiosis or roundworm? Three of the four that seem off are molting but other is a 9 mo old Buff Orp who has gone off lay but I assume shouldn't be molting yet?

My vet said they would give Baycox (tolgrazuril) for the coccidia and my local farmer's supply stocks Piperazine which I understand from the reading I've done is an option for worming molting hens.

Any advice is greatly appreciated!!

Treat them with the Baycox first. Then worm them with the Piperaziine, it'll take care of the large roundworms in your flock.
After worming your birds, give them plain boiled rice mixed with buttermilk to eat for a couple of days, It should stop the diarrhea.
