Jeeez, where to begin. Names and then associated nicknames... The majority of stuff gets named, although I balled my eyes out when I had to do Rodney my RIR cockeral; that was a real heart wrencher as he had been attacking the mother-in-law (woohoo) but then started going for my son (not woohoo). I tried to tell the boy he wasn't allowed to go out but that was a bit harsh.
We have the four ponies - Misty (moobags), Gracy (Growbags), Coco(nut - after his amazing surprise testicle) and Bella.
The two cows, Betty and Mooey, although Betty is sometimes referred to as 'Madame' after the cow in one of the kids TV shows. My two sows are Pepper and Petal, the piglets don't get names. Hercules the ram, which isn't his pedigree name, and my ewes are generally referred to by their shortened pedigree name although I sometimes call them number 1/2/3 depending on when they lambed last year which causes some confusion with this years lambs. We have Tiny Tim the Orphan, although he headbutts a lot of stuff so he's more commonly known as 'little bastard'. He does repsond to being shouted at 'TIMMMMYYYYYYYY' in Southpark manner.
Most of the hens don't have names, bar one or two. Ms. Barker springs to mind after my son's teacher. The cockerals have names; Rodders, Steve, Ronnie, Reggie and Charlie (Kray brothers - complete bastards and ran protection rackets on the yard, and Ronnie was a bit bi!), Jean-Claude, Jean-Piere (Favorelles), Biff (buff sussex who got covered in horse muck - Back to the future), Mike and Dave (after my father-in-law, he's a bit grouchy and a bit dim).
The only turkey that got named was 'One-eyed Wilimina' and we felt bad about selling her...
