Just went outside tonight to check on my flock and next to a few of my hens sleeping was a small pile of worms obviously one had just pooped out. It's was a mass of long tapeworms!! Several of them! I was so freaked out! I just dewormed the whole flock about 2 months ago with ivomec. I have about 65 chickens and the free range on about a little less than 1/2 a acre. I've read through lots of worm posts and people who have had tapeworms in their chickens say they only see little white segments. I realize this means at least this hen(she is about 6 months ) in particular has a huge worm load and will assume the whole flock is infested. Is this common or does this happen-passing large whole tapeworms??? They are def not roundworms. They are long flat and off white in color. Def tapeworms. To dark to get a pic. I've real valbazan is best to use? I'm just surprised ivomec didn't help at all?! I'm just so disturbed by these worms! Can they be passed into the egg?? And also can my dogs catch tapeworms from them? Thanks in advance for any advice!!!
