Okay, I know this is supposed to be 'easy', but I can't seem to figure them out. They all look the same! They are still quite young, but I believe they can be sexed at hatch? I have 7 that are about 8 weeks old, another around 6 or 7 weeks, 5 around 4 weeks, then another about 2 or 3 weeks. Any tell-tale signs I can look for? Some of the older ones are bigger than the others but if I remember correctly they weren't all the same size when I got them? I'll try to get pics tomorrow if you guys don't beat me up about their dirty building
