Hi All, I've been reading about the Wazine-17 first round followed by a second round of ivermectin to get larvae and a broader spectrum of parasites (thanks, threehorses!). I'm going to dose all 5 of my 16-month old hens since they have never been wormed. I have a very lethargic wyandotte who I began worrying about on Friday before Labor Day. By the time I figured out she probably had worms, the holiday weekend had kicked in and I couldn't get the wazine-17. I got it this morning and plan to put it in the hens' water at dawn tomorrow. My question is: will my sick hen perk up from the wazine? How long should it take? If she doesn't perk up, I'll suppose that worms--or at least roundworms--aren't the problem. But how long should I give it? Will the other hens--the ones who weren't droopy--be noticeably affected by the wazine? If so, how? I understand that I should give the girls yogurt after the wazine--24 hours after? Should I also try to increase their protein or vitamin intake? Anything else I should be on the look out for post-worming? Thanks!
