Most males feather out slower in the shoulder than females. Look at their legs. Males have thick legs. Also, look at stance. Make a sudden loud noise....do your chicks stand up straight or crouch down? (This is an old timers trick) LOL. Here is one of my males as that age.For straight run, yes. For sexed, 90%+
You SURE those birds are 5 1/2 weeks old? All of mine had more feathering than that at 3 weeks when they were moved to the coop in an unheated barn. It was the start of the second week of July, I did put their heat lamp facing into a big box in there the first couple of nights just in case - nervous new "father"![]()
Hope that doesn't mean yours are boys.
