Ive had my flock for 5 weeks, they are about 30weeks old, they were fully vaccinated and wormed on arrival.. I have used Verm-x in their water for three days. Does anyone else use this product? Is it effective? Its supposed to be natural but I have four small children so Im paranoid about worms! I would like to keep things as natural as possible. My birds are healthy and laying lots of eggs. I dont know how to spot the signs of birds having worms. Please help.
