You may need to watch them and see if they are really picking at one another.Yes I do put them together in one cage I usually do till about 3 months of age I’m not sure how many stags or pullets to me I think now two and two ósea two stags and two pullets I think not sure I might post a thread to see what they might be but there are 4 in total I actually need to change the cage since they are growing rapidly
Even pullets will pick at a stag.
You may find you need to put the pullets in one cage and the stags in their own - it's different every time. Sometimes they do o.k. for a while, other times not so much.
I'll be honest, I'm terrible at sexing birds LOL If you want others to see if they can tell, post on the Gamefowl thread the guys/gals may be able to tell. https://www.backyardchickens.com/threads/american-gamefowl.1307560/page-1606
