I just read and article in the Backyard Poultry Magazine (Apr/May 2013) called "healthy guts...healthy birds" where it mentions Zyfend as a safe natural alternative non-synthetic water supplement that has been proven in large organic and natural layer flocks to offset worm related issues without the need to discard the eggs.
I have not researched more about this particular product but wanted to know offhand if anybody has tested it and what their opinions are.
