are rose hips safe for bunnies?

I just wondered as my chinnie eats them. chico has a berry mix with rosehips, rowan berries, and others in it and i wondered if they were ok for bunnies?

not sure about bunnies but we fed them to the guinea pigs at college

*bump*

because I have a ton in my garden, and want to know if it is safe to feed some to the buns.

I know people who have fed them to horses with no problem...

rose hips contain tiny hairs around the seed. these are highly irritant both to skin and nasel tissue if inhaled, and should be removed befor consumption. (at least when fresh) im not sure what effect drying has on them though when you make jam it just be strained again and again through muslin so presumably the hairs are resiliant to high tempratures.
unless you are buying seedless rosehips (ie..seeds removed) i would avoid feeding these to rabbits
