I am more likely to name my roos and just use the band number from my hens legs or wings for my record keeping. When I collect eggs from pens that i plan to set eggs from I write the roo's name on it and record that for hatching. Before I got around 700 chickens I knew which egg came from which hen and could record that, as well but every summer I seem to climb high in numbers and spend all of fall trying to thin back for winter.
We can toss out names like Confetti, Party Boy, Ticker (like ticker tape parade). I had to name my first MF Frizzle boy Shazam because when I saw him maturing out I said it every time. Couldn't really call him *@&#(what holds back water between a lake and river)! LOL Though I said that a few times, as well, but really try to watch my fowl (ha, ha) mouth.
