Over last couple weeks a 3 year old gamehen had suffered from a worm load that was not roundworms. Based on appearance of worms in feces and failure respond to treatment for roundworms, the assumption was cecal worms. A more aggressive de-worming agent considered effective against all intestinal parasites was employed causing major passing of smaller worms about 18 hours post-treatment. Interesting observations are that prior to and for a couple days post-treatment the crop emptying rate was greatly slowed relative to rate of birds not showing worrisome signs of worm burden. This was even when amount consumed prior to roosting was the same. Now four days post-treatment appetite and consumption greatly increasing and weight is starting to come back up. The lag time was interesting. Also bird may have lost additional weight during treatment. Sick bird is also lagging with respect to molt and egg production stopped but will likely resume for a late season clutch.
