Hi! I found worms in one of my hens poo tonight. I just treats my flock with Corid for 3 days because I noticed on of my young pullets had a bit of bloody poo. Today one of my Americaunas pooed and it had long thin white wriggly worms in it. ( some alive- some not moving) Normal poo besides the worms. They have been on Rooster booster triple action wormer for about two weeks. Does this mean it's not working?! Help! I know in horses if they are pooping out the worms that means the wormer is working but anytime our horses poop had worms after being wormed they were dead. Half of the worms in the hens poo were alive and the other half were dead. Also- how do I treat my chicken run to remove all worms and eggs from the ground? I covered my run in DE about a month ago(2xs a week for 4 weeks) and my chickens dust bathe is DE. Is that enough or is there something else to do?
