diarrhea and watery poop

[Harestad Farm]

Hey guys, new to this site. Ive been struggling with diarrhea light brown squirts and some very watery and foamy. a couple weeks ago I had a bloody (really bloody) poop outbreak in one hen. I treated the whole flock with corrid for 5 days and all the poops cleared up. but recently things seem to be getting nasty again....I really think its getting caused my their living conditions.
I have 6 layers (just beginning to lay, various breeds) and one rooster (I think he is , though he hasn't crowed yet) We live south of Seattle and this time of year it gets really rainy up here. My chickens live in a 5x5 coop that opens to a covered 10' run with a perch area. Around their coop I built 30x20 pen (to protect them from predators... and my Huskies, since i dont think they'd play nicely) that they run freely in during the day... now do to seattle weather, their whole pen has turned into a poop/mud pen, except for the covered portions. I've switched their watering source from watering trays to a food grade 5 gal bucket with watering nipples. They drink from it but I just dont feel they are getting enough water from it since they are still scavenging for water on the ground when it pools up from the rain, which cant be healthy. Ive hung their food tray up to keep that free from mold, moisture and poop. And on the weekends I put the dogs up front and let the chicken rrun free in the back yard. but i think the muddy poopy pen is a key contributor... I just started adding a supplement to their water.... any help or pointer or advice would be much appreciated

Can you try to get a fecal float done on some fresh droppings to look for repeat coccidiosis or capillary worms?

It might be necessary to do some landscaping to get the water to run away from your coop and run. Sand drains well, and you night be able to find some free nearby or have a truckload brought in. Cinder blocks or tree stumps might be good to keep them up out of mud. I would definitely add another water source (and food if possible) just in case of a malfunction or bullying. A large black rubber pan up to chickens shoulder height on bricks can help in keeping things dry.

Certain strains of coccidiosis can be chronic. Keeping bedding stirred and dry is the best way to control coccidia.
