2 Males together in Pen?

[Marjoriesanderson]

Hi there! I have a male and a female in a very large pen and run, and a place they keep warm at too. I turned one of the 3 year old male offspring out to free-roam this past spring, and it stays close to the pen and roosts in our trees next to the pen. It is about to get FREEZING here for a few days, and I thought I might put the male back in the pen with the adult male and female for those freezing days to keep warm. Do you think that will be ok with the 2 males in the pen together along with the adult female (the young peacock's mama)? I have a heater in the pen and just want to make sure he doesn't get sleeted & snowed on at unbearably low temps. I would let it back out after.
*We have a very large barn/shed it could get in if it was smart enough, but it hasn't gone out there for shelter at all since we let it free-roam.
