I've changed my rabbits hay

ive changed my rabbits hay to good quality farm hay i got from a local farm, they love it and are munching it all day. 1 problem.... ive noticed thier poos have gone a lot darker since i changed it about a week ago. Is it something i need to address or not?

thanks

My rabbits' poo colour changed when they went out onto grass, so maybe a change of hay is the same? :? as long as the quantity or size of the poos doesn't change, then I don't think it's a problem.

yeah don't worry about it unless the size changes dramatically. My two have golden poos on oat hay and darker ones on grasses and meadow hay!!!:roll::lol:
