We have an ill 5 yr old Leghorn we took in last November. I'll list history, symptoms and treatment we've employed but I'm sure that there will be more questions. Janice is nearly 5 yrs old rescue Leghorn with only 1 previous respiratory illness (1yr old), no longer is laying. We quarantined her of 1 month on intake and 2 weeks into her arrival she started to have diarrhea with runny green droppings and watery fluid surrounding the droppings. Otherwise she was active and bright eyed, feisty with the flock when integrated so we downplayed the issue. Our flock had Fowl Pox during quarantine period (dry variety) but she never had symptoms. (2 Americaunas, 3 Australorps - 1 yrs old). We've integrated her with the flock (December) and she has fit in at a low status with not much trouble, some challenges getting her to eat. We coddled her too much with treats of tomatoes and strawberry tops - she had a recurring case of sour crop for last month (January) - finally treated with Monistat (generic) and seams to be clear this week...so far. For food the flock gets garden greens, some kitchen scraps, organic crumbles with occasional meal worms. We add ACV to water (not while we were treating sour crop) and probiotics in food (powder and as plain yogurt). We've cut out all fruit since she got sour crop. They free range each day and have access to grasses and desert / vegetable garden yard (so she may have eaten ANYTHING by now) - she was free range 100% before so no change. She's been quarantined 3 or 4 times for up to 4 days at a time since late December to clear up the sour crop, first we tried regurgitation, olive oil, and crop massage to rid any blockage and diet changes but it reappeared after a few days each time we reintroduced her to flock. The regurgitation never worked well, we mostly worried about further respiratory issues. Each time we quarantine her she acts depressed, barely eats even mealworm treats. She's happier with our girls, even at a low status. The diarrhea has continued, her bum feathers were so coated we trimmed them away and have to clean her regularly, no signs of distended vent or infection there. Monistat treatment is hopeful but doesn't address the diarrhea issue which is declining. We treated the whole flock for round worms in December (Wazine 17) and have always used DE in coop, food, and run. We retreated her again 3 days ago - no positive changes. This was recommended by local feed store but haven't had any signs in droppings of worms before or after treatment (I'm not shy about digging around to see what was in their droppings) Today, she is showing signs of weakness, droopy wings and tail feathers. I'm not willing to pay for a vet, yes I know it may help, but I have enormous medical bills so I have to prioritize. It may just be her time but I need to try every resource I can and the BYC sites have always helped with our first year of chicken raising so I hope this will help again. Thank you for your time!
