Hello All, I have only been a hen owner for a 3 weeks now but I have a buff cochin that was so many worms it is unbelievable. My hens are all about 1-2 years old. I got them from a woman that sold eggs at the farmers market and had over 150 chickens, but she is off to vet school now and had to sell everything. I have just 7 birds. I live in the very dry desert southwest and they free range, they have access to 2 acres but really only use about one. My cochin, has been very docile, not moving around, staying in one spot all day, not roosting at all. This has gone on for 3 days. When we got a hold of her today, we gentle moved all her feathers on her vent aside and she is covered in fecal matter and 30 to 50 worms just crawling everywhere. They were about 1/4 to 1/2 inch long. They were gray and easy to remove(other than how many there were). We stopped removing them when my husband brought up contamination. We have put her in her own area and have not checked the other hens as we have been frantically searching the net for what to do now. How do we help her? Do we clean her all up and try to remove all the worms. Do we just use a product like Wazine 17? Also, we had followed the info on this site about deep littering method for coops. Do we clean it all out, scour it down, what? Also, everyone recommends DE. I have checked both supply stores here and neither one has ever heard of it. Are these worms a risk to my cats and dog or my 7 beautiful children who love to help and have been out with the chickens everyday? Any help you guys can offer will be much appreciated. Thanks for taking the time to read my post.
