Worming

I need to know what kind of wormer to use for 3 hens. I went to Tractor Supply today and they said all the wormers made in the U.S. you couldn't eat the eggs for 30 days afterwards and that I'd have to look in Europe or someplace and order some. I have a hard time believing this! I've only had chickens for about 3 months, so I'm confused as to if I even NEED to worm, as they seem very happy and healthy and only get dried mealworms, a laying crumbles feed and lots of whatever table scraps they'll eat: mainly seeded fruits and leftover corn on the cob or bread products. I have two Rhode Island Reds, about 6 mths old and 1 Amber Link that I was told was only about 6 months old when we got her, but I believe to be MUCH older b/c we knew nothing about chickens and had originally gotten her with a supposedly young Golden Comet. When the comet went "belly up" less than 2 mths after we bought her, I pretty much assumed the guy we bought both from was lying. The Amber Link has produced MAYBE a dozen eggs in 3 months, so she's probably towards the end of her laying cycle, but I love her and will keep her until she dies. Anyway, if anyone can help with the worming question, I'd greatly appreciate it! Thanks!

 

Yes, we have them in a run about 6 feet long by 3 feet wide, completely enclosed with chicken wire. It has an elevated coop about 2 1/2 by 2 1/2 at the end. We just moved them to their winter location so they have fresh grass/dirt to peck in, but I have a covering of shavings down as well, just to try to keep the odor issue under control since they are so much closer to the house. It's much easier to rake it than have them standing on mud after the grass is beaten down. They're getting dried mealworms and occasionally I will make a foray to the live bait store and get them some wax worms and/or nightcrawlers. Someone else told me pumpkin seeds acts as a natural wormer too. I will check on the name of that wormer you mentioned and thanks!
Also, thanks for the welcome! <G>

Let me clarify that I also feed them laying crumbles and lots of table scraps! They don't just get worms and dried mealworms, lol.
