When I moved my 7 geese from South Florida to west central Georgia in 07 I lost all except 3. Those three seem to be smart enough (or skittish enough) to beat feet for the lake when ANYTHING moves that they aren`t familiar with. I bought 20 guinea keets in July `09 and they were all taken except for three. Neither geese nor guineas can hatch any eggs as the eggs are destroyed within 3 days of starting a new nest. If either was to actually succeed in begining to brood, I`m sure I would lose that bird also. Dogs are the best deterrent, but ya gotta have two and socialize them with the fowl early. Two work together, but one usually just lays around until there is a comotion. Good luck.......Pop
