My almost 5 months old peafowl (2 males) are getting bigger and bigger. I built them a well isolated shelter in my back yard and always keep the temperature above 10 degrees Celsius (50 Fahrenheit) - most of the time it's around 15 Celsius (59 Fahrenheit) - using an electric heater- well out of their reach).
I had to leave for 3 days for Christmas and I left my aunt to come check on them and give them food and water. When I came back one of my peacocks was missing his crow! I asked my aunt what happened and she said she hadn't noticed it went missing. I am very worried. I attached a photo of them. The one in the front as you can see has very small feathers just barely growing while the other one has full grown ones. Before I left they both had long ones like the one in the back.
Should I be worried? Is it normal - do they shed their crown at such an early age? Do you think they could be fighting ?( they don't seem to be, they always sit next to each other and gently peck at each other's beaks - I have never observed any violence)
The shelter I built is just for the winter and its 2m x 2m (6,56 ft x 6,56 ft) - I built it so small so I can keep it warm easily and as I have said the temperature is always over 10 degrees Celsius - Do you think the space might be too small? Or too cold for them and that's why they lost their head feathers?
