chickens and horse manure and dewormer.... oh my!

[SweetSilver]

I'm curious about horse manure in the organic veggie garden. Horses are dewormed on a schedule every 2 months. I know gardens love the manure, but is the dewormer persistent?

And here is another important question.... should I keep my chickens off it? Segregate the manure after horse worming only? Again, how persistent? I like the idea of running chickens over manure and pasture, but I worry about exposure to dewormer and whether it affects their eggs, even though the chickens themselves are not being dewormed?

Has anyone thought about this or know about this?

I hope I'm making sense, and I didn't know where to post this, but since it's all going on the garden.....

It's my sister who has the horses (for now).

I'm sorry there wasn't an answer, as this is a good question. I have a garden and use steer gro so... wish I knew.

Thanks for bumping this thread, I've been offline for a while.

I think it's a good question, too, and I'm having trouble finding an answer. Guess I need to stop being lazy and do my own researching.

Meantime, I bumped this thread again, just in case I get an answer the lazy way.

My circular garden system includes chicken compost, to garden beds, cuttings to vermiculture, and worms back to the chickens. Everything I've ever heard or read says that the worms don't handle manure from horses that have been recently wormed. I haven't wanted to try it to see how serious the impact might be. Good luck!

So.... what time frame is "recently"? Clearly not the day after, for sure, but how about a week? Longer? They are wormed every 3 months usually.
