By the time they get to six months I am usually VERY keen to see the back of them - too much pushing and shoving for their food, risk of getting pushed over and very noisy if you are a few minutes behind schedule with the feeding bucket... but then miss them for the first few days, until the stuff comes back from the butcher.... We had the first taste of this years (homemade) sausages, well worth the pushing, shoving (and fighting the wasps off the fruit/veg I collect from the greengrocers all summer!!!!!).
