Ive been doing a lot of readings and read upon vent checking and checking wing feathers. How accurate are these methods? I have some Ayam Cemanis Im trying to name from A-Z but its kind of hard to not know gender. Feather checking looks easiest and which would mean of my 7 chicks they're all female? Vent checking I thought I had a male, but now Im starting to doubt what Im looking at when vent checking. Any help?
