Our five chickens are free to roam our 1/3 acre pasture which is fully fenced. We want to overseed and fertilize the pasture grass soon, but are concerned that the chickens will eat the fertilizer granules. We usually use straight nitrogen granules for fertilizing our lawn and pasture. Is it likely they'd just take a little taste and then move on to more interesting things or would they make a meal of the granules? Any recommendations? Thanks!
