Okay.. I noticed to night that my chicken wasnt acting like himself and that he'd formed a poop clot on his butt. So I took him inside to clean it off. When I was done, I decided to get a close look at his butt to make sure there was no infection. It was covered in worms!! I almost puked on my little guy.. Not only is he covered but he's swollen and bloody. I rushed to the store and got a de-wormer. I just gave him his dose and I also poured a bunch over the worms in desperation. I dont know if that'll help or not Is there ANYTHING else I can do?? How long does it take the de-wormer to work?? How often should I give it to him?? I'm desperate for help.. this chicken is extremely important to me! Please let me know if there is anyway I can get these worms off, I've tried picking them off one by one but there are too many and they are too fast.
