I need to sex my geese. The only way I know who's who is when I see them mating. But when the act is over they all go back to looking alike. So I thought I'd use temporary collars in different colors so I can see from a distance, for instance "ok, the yellow collar is a male." AND THEN I CAN BAND HIM.
Of course, they don't mate when I'm standing over them so it has to be visible from a distance. Is there any reason why I couldn't put some kind of a temporary collar on them for a day or two? I was thinking maybe a loose zip tie? Or, I don't know, a bandana?
I thought I was being real smart when I hit him with the paintball gun and left a big orange mark on him. Until they all went bathing.
Or maybe I could paint a collar with waterproof markers? I just need to use it for a couple of days till I can make sure who's female and who's male and give them permanent bands.
Any ideas?
