I got 3 pullets (and 2 more birds of questionable gender) about a month ago from a local, they are now about 16 weeks old. I'm still not sure about one, but the last is looking more and more like a cockerel to me. Here he/she is: Here is the suspect (far front) with some of the others, they were not feeling photogenic last night. The one in the far back is the other one we were not sure of: Here again is the other questionable one, but I'm leaning more towards a pullet there: I've heard marans take a bit longer to mature than other breeds, and I'm new to chickens, so I'm not sure how long I wait to be sure on these. They are all about the same size, with one or two of the pullets a bit smaller than the rest. I wasn't really planning on keeping any roos, but there's nothing prohibiting it where we are either. I took them thinking we could always eat any that turn out to be roosters. Any thoughts?
