I got these chicks 2 weeks ago at an auction. There was a pen of 5 buff? and a pen of 5 bronze/5 Lavender. They are very skiddish, so the pics aren't that great. I tried to get a pic of them in the cage, standing, but they would stand still long enough. The buff? I have 1 dark and 2 light, friend has the other 2. I read somewhere that the dark ones are hens? They are older than the others, they are starting to lose the fuzz aroung their necks, and they are about the same size as my 2 month old (chicken) chicks. the darkest, cream colored with brown wings/tail One of the light ones, cream colored, slightly darker around the wings/tails Lavender, smaller than the buffs, but it looks like they(lavender and bronze) are 2 different groups, possibly a week apart. And lastly, the bronze, 2 of them have white wings, does that mean anything? When do guineas start to lay?
