Hi all, not sure if my flock has a worm problem, but would rather be proactive. I’ve noticed some weight loss in my rooster (though he’s by no means bony) and another rooster with a dry red vent, so I figure it’s time to start them on at least a preventative worm treatment schedule. What is the best dewormer, whether chemical or natural? I would like to avoid egg withdrawal if possible, none are ready for slaughter any time soon. Thank you!
