I had a sick chicken towards the end of June (one died before that for reasons that are still unknown). I gave her molasses water, acv water, a couple of warm baths and out popped a load of round worms after she expelled a shell from the shelless egg I saw her lay and a rubber egg). I put them on wazine...didnt follow up with another round of wazine or other broad spectrum wormer. I decided to use verm-x instead...herbal wormer...no egg withdrawal. Well, chickens didnt get better and a few weeks later (after having eggs for a week) saw worms moving in poop. All I had was wazine so I treated them, but then I started talking to dawg53 (the worming guy) and decided to worm them with valbazen at the end of July. I then dewormed them 10 days later, and now am waiting until the 25th of this month! Basically I wormed with wazine, tried to go natural, wormed with wazine again, then because it is supposedlly not that great had to worm with valbazen and then valbazen again. In the meantime, my girls got cocci, and they have some respiratory issues too now, so I treated with corid and am now treating with denagard! What a summer! Never thought I'd be medicating my girls!
