I was going to give our girls (let my 10 yro make them some hanging snacks) some bagels with peanut butter and birdseed on them. Is this okay, or should I use something else instead of the PB?? Also what should I hang them up with? I was going to hang 1 or 2 in the run and 1 in the coop. Got bagals cheap at Wal-Mart the other day, so I wanted to use before they mold. We usually do this for the wild birds in the winter and just hang with a piece of yarn, but I don't want our girls trying to eat the yard.
