So yesterday I noticed an ill chicken. Well when I went out this morning she had passed I looked her over and didn't find any reminents of fleas, ticks or mites. I then proceeded to investigate some poop. There was possibly one worm in one pile. It was white and very small. I am thinking I should deworm? I didn't find any others but just in case. What do I use to deworm? Do I have to toss the eggs while I deworm?
