Hay Is this mixture of hay ok to feed guinea pigs?

[sdpiggylvr]

My local House Rabbit Society sells a large box of mixed hay with orchard or meadow grass, rye grass, Timothy hay, Bermuda grass or oat hay. Is this mixture ok to feed guinea pigs?

Rye and Oat are grain hays, not really good for daily feeding. If the amounts of those two types are very small you can use the mix.
