After calling several vets none have an exact answer and none test for this! My kids have had a reoccuring pinworn infection, do not go to day care and I have done the medicine/cleaning and 6 months later still have it! SO I searched online and it said a chicken with pinworms will look rough and not recover from molting...I have one chicken like that. My children get the eggs, so I am wondering if this is the problem?! They are not pets, just for eggs/food, so if I had to get rid of them fine, but I just need more answers! HELP if you know anything !!!!
