I currently have 2 hens. Previously I had four. I lost one in mid summer and another on Christmas. Both seemed to just drop dead, with no explanation. Neither seemed sick. This past fall, I installed a droppings board and use SweatPDZ underneath the roost and clean poops daily. It has allowed me to notice abnormalities and has caused a HUGE improvement in my winter coop (I am in Minnesota and the current temp is -17.) The two remaining hens have the following problems: Hen 1 has a gurgling sound almost all the time. Hen 2 has chronic liquid poops that run from dark mustard to greenish black to whitish green. OCCASIONALLY they are normal. Both hens are laying normally, eating like fiends (normal) and drinking normally. They are active and seem fine, aside from the above descriptions. Several weeks ago, while cleaning the droppings, I noticed what appeared to be thread-like white worms in one of the poops. I have never seen any since. Immediately, I researched that on BYC and bought some Wazine and dozed both hens. Neither of the above maladies were improved. So I came back and researched some more. I bought Vermex and dosed them approximately 3 weeks after the Wazine. That was about 2 weeks ago. Still no improvement in runny poop or gurgle sound. What now? Please advise. (please note that while I love my chickens, I am not a "bring them in the house" owner. Been there, done that and they still died. I've been raising chickens for almost 15 years and I've never really had any problems, so this is new. I love them and will do what I can, but it does not include vet trips or more than $50. Hope that doesn't sound callous, I'm just trying to preclude any advise that has me making them a better breakfast in the morning than I eat myself.
