Thank you both so much! That does help. Here's another question: I have a variety of colors. Some I can tell by the color of their breast feathers if they are male or female, but others I cannot. Is there any way to sex them if they are very dark or if they are white (or have white chests)?
Also, I have read about the colors, but unless I've missed it somewhere, I can't seem to find the color description with a photo that I can compare mine to so that I can know the names of their different color patterns. I know it has to be somewhere, I just can't find it!
ETA: I don't think they are old enough to vent sex yet. Am I correct?
