Hi sorry I have climbed onto this thread a few years later than your original post but I had the same thing happen to me and I am totally dumbfounded. I too have what I thought was a Jake as it would puff itself up and tilt the head and the drooping snout the whole works. I bought a huge tom with two female so I locked my jake up in a cage overnight (scared thinking the new Tom would hurt him) but this morning I went and found a egg in "its" cage. I then let "it" out with my other "females" that I bought and "IT" immediately puffed itself up and tried kicking the two new "females" The two new "females" also puffed their tail feathers up and kicked, behaviour which you'd expect from a male. So are my new females also males they are still youngish and the two new "females" are white and mine is black so could this be the reason. I am so confused now and was wondering if females also fight with other hens. what was the outcome with yours?
