Does the peanut butter spoil or freeze or anything like that?
My grandmother once had an orange out for the birds that sat too long and started to soil and ferment. She had a couple of drunk birds for a while.
there is so much oil in the peanut butter that it will not freeze very fast.
I don't think it spoils due to the cold.
Mine is a bit to close to the house so they come now and then.
I heard story's from people who need to replace the jar every two weeks!
