I have been trying to sex my buttons. I remember someone saying that you could tell them apart from their vent feathers. Red vent feathers means one or the other. I just can't remember. Please let it be that red vent feather means I have just a few males and a whole lot of females.... However I think that it is the other way around. Please let me know Also if anyone could help me with what colors I have that would be great. I have an idea just want to know for sure. Think I have alot of mixes.
