“Four and twenty blackbirds” might make a dainty dish “to set before the king”, but when it comes to your farm, you might like them more… if they just “flew the coop.” A look at the quantity and value of feed that birds consume may reveal that they are costing you far more than the “sixpence” mentioned in the classic nursery rhyme. Just how much are birds stealing from you? How much are birds on your farm costing you? Here’s a look at some numbers and information, which is based on new data from a recent survey. The survey was conducted 2009 by the USDA Animal and Plant Health Inspection Service (APHIS). Their survey reported the results from 399 commercial dairies in Pennsylvania, New York and Wisconsin. Results were published in the November 2012 Journal of Dairy Science. The information can certainly help us to better understand the magnitude of feed losses caused by birds on dairies.
