I made this post on another chicken forum and got some wonderful answers. Now I know how large Backyard Chicken Forum is, so I am looking to hear some more comments and replies. Below my post, which I have placed in italics, I will also cite a quote from another site that speaks about chicken parasites, inside and outside. Worms are host specific. If this is tapeworm segments that I have seen in this feces, it is chicken tapeworm, dog and cat tapeworm are of a different species of tapeworm, just as an aside. So, some time ago, I was in the chickenyard and noticed a big poop, yes a very big poop, so big that it was very noticeable, and being the curious creature that I am, I needed to look closer. And that I did. What I saw gave me the heebie geebies, so I looked closer. What I saw turned my world around. I thought my chickens were free of internal parasites, but clearly, as that day is long, were not. After seeing this, the following day, all the birds got a good dose of piperazine, and then a followup treatment, as the designated time. Thinking now that they are internal parasite free, smiling. As I looked at this rather large and disgusting piece of poo, I was looking at the little white sacks of something or other. I can only presume that these little white sacks were little white sacs of worm eggs. I don't know, and I would love to know, what these little white sacs of who knows what actually are. The little white sacs of something-or-other moved. Yes, I looked closely and they were moving. Are they sacs of eggs. Are they immature worms, pleeeeeeze, someone must know and must have seen this type of thing. I don't think I am the only one that really examines things in close perspective. This grossed me out more than you could ever imagine, it was a nasty experience, one that I don't ever want to experience again. I put that nasty big poop and all its nasty little white things moving into a ziploc bag and thrust into the burning barrel. Burned it all up, but of course, for the sake of my sanity, and someone actually believing me that this kind of thing existed, I took that picture....and that picture of that nasty poop with all those little white thingies is here now, for all to look at. And comments would be so welcomed, tell your experience, and, well, does anyone have any pictures of some really nasty poop. When I looked at that website that showed all the many forms of chicken poop, I was so shocked and surprised at how many different types of surprise poops chickens actually have, smiling. Beautiful days, those ones of love and health and peace, CynthiaM. The most grossest thing I have ever seen in this world!!! But hopefully, to never see no more This is a site that talks about these parasites of chickens, a very good read http://msucares.com/poultry/diseases/disparas.htm Below is the text from the above link, if one does not want to go to the link and read about the parasites Tapeworms Tapeworms or cestodes are flattened, ribbon-shaped worms composed of numerous segments or division. Tapeworms vary in size from very small to several inches in length. The head or anterior end is much smaller than the rest of the body. Since tapeworms may be very small, careful examination often is necessary to find them. A portion of the intestine may be opened and placed in water to assist in finding the tapeworms. The pathology or damage tapeworms produce in poultry is controversial. In young birds, heavy infections result in reduced efficiency and slower growth. Young birds are more severely affected than older birds. All poultry tapeworms apparently spend part of their lives in intermediate hosts, and birds become infected by eating the intermediate hosts. These hosts include snails, slugs, beetles, ants, grasshoppers, earthworms, houseflies and others. The intermediate host becomes infected by eating the eggs of tapeworms that are passed in the bird feces. Although several drugs are used to remove tapeworms from poultry, most are of doubtful efficacy. In general, tapeworms are most readily controlled by preventing the birds from eating the infected intermediate host. Tapeworm infections can be controlled by regular treatment of the bird with fenbendazole or leviamisole.
