Question:
I understand that fertile rate for Cochins is about 50-60%.
I also understand that trimming the feathers around their vent can increase that rate.
Is this considered a natural practice?
for show quality bantam cochins, yes that is pretty much the norm... many do AI so they don't have to trim fluff, if they're conditioning for a show as well. for hatchery quality cochins, no you don't need to because they don't have that thick heavy underfluff like the show quality ones do.
is it natural? no, is it necessary? if you are breeding show quality, without trimming you may not get ANY fertility... it just depends on what you want, and what birds you're working with. I have one new boy who will need to be trimmed, but most of my other boys seem to manage just fine on their own.
trim the hens above the vent, the roo below the vent... if you scissor it too short the girls will get stabbed by the stubble/feather shafts. many prefer to pluck. personally, I use scissors and just trim the outer edges of the fluff, down about an inch or so each time, until I start seeing better fertility in the eggs. maybe once a week or so. if the stubble gets so short that it's starting to irritate the hens, then you need to pluck.
sometimes just plucking some of the fluff to thin it out works as well, or a combination of trim and pluck. it's up to you.
