Comb to gender theory accuracy?

[chickenchick2714]

I’m hearing that as far as the pea comb goes 3 means a male and one means female has that been accurate for you? Has anyone noticed what they thought was a pullet develop a 3 row pea comb and turn out to be a male or still female? Also with tail feather developing later has then been accurate or inaccurate for you when it comes to sexing? Just curious!

I know that the feathering only works accurately with certain breed combination. I don't have birds with true pea combs, but I believe the pea combs are different between pullets and cockerals if they are true pea combs. In my experience it doesn't work well with modified peacombs like EEs often have.
