Worm Diagnosis kit contains container with lid for collecting sample faeces which is placed in the clip lock bag provided. In this case you pay for the kit and all the rest is free , rather than a "free" kit being supplied and you being charged later for the actual test. This bag is placed into the supplied Replied Paid bag to send to Parasite Diagnostics for analysis.
This is a very good idea to ensure you know what worms are actually present in the chicken coop or in your ducks and poultry in general. That way you are not unnecessarily dosing your flock for things that may or may not be a problem.
On the form supplied provide your email address for diagnosis results.
