So is everyone going for orange?!
I usually start with yellow, then orange, green, red, blue, black. That was back in the old days!! Swore by the harness. Nettex one with the all-weather chalks.
But last year, flys got under the straps on his back and maggots appeared under the harness. Never a good thing to start with and especially when its not my tup, so off to the shops and back with blue powder. This year, saw the powder on offer so for my massive flock (5) bought some more tubs. Started with yellow, then got to the orange. But the heat in July meant that the girl who got seen to first had bright butt, but the others then went paler due to melting (the wax). But never mind, rubber glove (me) handful of goo, bucket shoved under his nose and he's recoloured!
