hey folks, looking for a bit of help. 2 weeks ago i noticed one of my pullets was limping. i tried to catch her, but she was too quick. By the next morning she was unable to walk at all. So i brought her inside to care for her. i assumed she had a leg/hip/pelvic injury. So i fashioned her a sling to take the weight off her back end, and gave her a little aspirin and food and water. She was eating and drinking fine up until about 4 days ago. When i went to check on her she wouldn't open her eyes. She kept snapping at the air and acting like she had something in her throat. (not gaping like gapeworm). She stopped eating and drinking and started doing a weird head sway and had a couple of short convulsions during the day. i gave her electrolytes with an eye dropper and tried to get her to eat some yogurt. i didn't expect her to make it through the night. The next day she was still hanging in there. i continued with the electrolytes w/vitamins, aspirin and started her on tetracycline. She started looking better, cracked one eye open just a little and stopped the head sway thing but still not eating or drinking. She was still acting like she had something stuck in her throat. Opening and closing her mouth like she was chewing. i looked in her mouth but couldn't see anything. Last night i went to give her some water with a dropper and notice her beak was full of clear mucus. Did a little research online and thought it was possibly sour crop. So i flipped her upside down and a huge glob of clear mucus came up. It didn't have any smell though. i gave her some epsom salt/water to rinse the crop and then started her on water with ACV. This morning she had both eyes half open and was sitting up looking pretty good, but when she tips her head forward she has clear mucus leaking from her beak. i used a q-tip to clean out her mouth. Today i've given her a little aspirin and tetracycline. Everytime i give her water, mucus drips out her beak. i keep checking her crop and if feels squishy like a water balloon (she has only had liquids for 3-4 days) but it doesn't seem to be emptying very well. i haven't given her any liquid in an hour and a half and it hasn't gone down at all. She did make a small amount of poo today though. i'm at a loss. i'm not sure what else i can do for her. i've been raising chickens for over 10 years and have never come across anything like this before. i thought the leg problem was injury, but with the weird neurological stuff she had going on it might be something else. She is 5-6 months old, not laying yet. She is not coughing, sneezing or have any respiratory issues other than the mucus in her beak. It's not coming out her nose. Does anyone have any ideas? thanks!
