Does anyone else have trouble getting their buns to eat enough hay? I've ordered Poppy a sample pack, but she's not been eating much hay lately. Her teeth have been checked. I was wondering whether to cut her SS down - she has a small handful morning and night. She finished it up very quickly this morning but I don't think she's eaten much hay. Have also offered readigrass and Friendly dried grass, but she doesn't seem very interested. Has anyone used the Oxbow hay cakes?
