Okay, so, my chicken is a white leghorn (female). We've had her for about a year now, and never has she before had any medical problems. Just recently, we noticed her foot was bloody and "beat-up" so we picked her up, and washed off the blood. There wasn't much we could do, so we just kinda let her heal herself up. A couple of days later, she suddenly just DISAPPEARED! Knowing we have raccoons around, we assumed that they had gotten her. A few days had passed since her "death", and there was still no sign of her. Today, I went to go feed our chickens, and I seen she was there too! We thought this was the end of our struggles, but this was only the beginning. She wouldn't eat, drink, or do anything other than stand there, trying to breathe. She is trying so hard to breathe, that she CAN'T eat or drink! She just stands there, stretching her neck out, and opening her mouth on a continuous loop. Now that I think about it, I seen her doing this in her coop before, but thought it was alike to cats when they smell something such as another cat and they just sit there with there mouth open for a small bit of time until they move on (haha). I brushed it off as funny, and went on my way. Now, I wish I would've payed attention sooner, as I fear it is too late to do anything about it. We read an article stating to add a teaspoon of vinegar to there water, and we did this so the others won't become contaminated with what we read appears to be a gape worm. She, obviously, cannot drink the water, as she is TRYING TO BREATH. May ANYBODY please help??? I don't know how to save my chicken!!!
