I need a little advice, I am new to cuckoos and I just culled down to 3 little roos to keep. They are young, about 3 months at most, and I just picked them based on nice barring and no white feathers, feathered legs. One I culled was light in his hackles but not his body, kinda like a pullet would look. I am thinking I just need to let them grow up a few more months and then take a look at them again. At this age I don't think there is much that they can be culled for right? I have some younger ones too that are blue cuckoo and I will look at them in a few weeks and cull the same way if that was a good culling technique at that age

I didn't see any gold leakage.... that was a big deal too.
