Horses and sheep?

Is there anything wrong with having a few sheep in with horses? They get along perfectly, but I heard there may be a health reason not to do this? Thanks!

All I know is that all the horse feeds state "do not feed to sheep". Must be something that doesn't mix with the two.

No problem as far as I know. Neighbour has broodmares in with sheep all the time, and has never had issues.

Wild_spot, they had sheep in with the horses at PC for a while as well didn't they ???

Yes, forgot about that. For ages, no problems. That was only 4/5 sheep though. The broodmares were in with a whole mob.

Oh yeah I don't see why it would be a problem. :)

Only problem as long as they get along is check the feed you give the horses if its a commercial feed. If it has Copper in it that can kill sheep

Also, I wouldn't put horses in with ewes who are lambing. We had an incident where one of the broodmares stepped on a lamb and broke it's leg :[

Ohhh poor thing. :[

Thank you for all your replies! The horses are fed grain in their stalls and then have hay in the pasture, so there is no chance of the sheep eating thier grain or anything. I am aware of the copper issue and am super careful. I only have 3 ewes, they are just pets so there wont be any lambs to get underfoot either lol. I do have a bottle lamb, but he is kept seperate. Thanks again! Heres a pic of my darling bottle lamb, Lyric.
