I used to be excellent at determining gender because I had a lot of one breed - brahmas - and they are very easy to sex at a young age. My seramas are pretty easy to sex too. Now I have two new breeds that I'm in love with - cochins and bredas - and it's proving quite difficult. I have a BYC/personal friend that is an expert on cochins. I had named a cochin pullet Norman when she was still quite young, but Norman quickly became Norma. My friend agreed with me on Philip, but Philip is a cochin frizzle making her harder to sex and she has remained Philip. We were used to calling her that and the name stuck. So far with the newest chicks we have: A Sou (Sue) a cochin rooster, a Rayne (got that one right) the hen, and a Rita the rooster. So, do you change the names when the gender turns out to be the opposite of what you guessed or do you leave them the same?
