Hey Corvid, Up until 15 years ago here in the south our hog lots were like yours, now they are all in houses but back then we used to hunt doves in corn fields where the farmer would turn the hogs in the corn.  The same thing would happen as you experience.  They would eat them as fast as they would hit the ground.  You had to be quick to recover the bird or lose it. Cool picture.

Gary, we seem to have gone full circle here in the uk, as years ago the pigs were reared outside then in the 70s the craze for intensive pig rearing saw the pigs all in side, and now we are back to rearing them outside again, which im pleased as to see all the pigs chained by there necks in stall houses was never a good sight, and to see them now running around outside enjoying there short lives is much better, they even farrow in huts which are in fields so the piglets are soon outside running around, as you can see in the pic they soon come in to your decoy layout, LOL. Zeddicus we dont have any problem with the lead issue with pig farms over here yet, i know some of the organic reared pork wont let you shoot due to the lead, but the pigfarmers are more than pleased to see you shooting crows, i even get help with the cartridges on a couple of farms, but im sure it wont be long before they start making you use steel shot, but it will be so exspensive no one will bother to shoot the crows.
