This explains the adage: "_____ a blue streak"

People often ask us how much of our crop is eaten by "birds". We hardly notice any significant consumption by birds, until yesterday. Looks like our own "birds" are sneaking in and getting an early start on the harvest. Couldn't catch it on video, but this one was earlier hopping up to get berries from the bush. We have noticed that just recently the chicken droppings have a "blue" hue to them. Despite the blue manure around the place, the bushes are still NOT ripe enough to pick. We normally open when the dog droppings turn blue. Will update again on Tuesday of next week. Keep your fingers crossed and we will start locking up the chickens.
