i'm not sure about raw food with those animals. i feed apples to deer and peanut butter on bread to squirrels. that's my favorite because the squirrels just eat the peanut butter and leave the bread. i think it's cute haha i'm sure you could use carrots or celery though. i know groundhogs like lettuce and carrots because i've fed them at the game preserve. how bought raw sunflower/pumpkin/hemp seeds for birds?
I read on a site that after you use wheat grass seeds and harvest the grass, that the birds will like to eat the seeds that were used. If you don't grow wheatgrass I guess you could still sprout the seeds in a jar for them. (The seeds are sprouted before they're planted.)
