Put them together and use the zip ties. That's what I use and I will if I have the rhodebars and CCL hatch together. I've heard they look alike when hatched.I guess I have been trying too hard. Thanks to everyone here, I now have breeds that I have never had before. I have been trying to keep them apart so I could watch how each breed grows, keep track of male and female, that kind of stuff. I have been tempted to build a "chick" pen in the middle of the barn and put them all together. I bought tiny colored zip ties to put on different breeds to tell them apart, but haven't been able to make myself put them on those tiny, tiny legs. I have also worried about them picking on each other. Should I just put them all together??
