Peacocks are wonderful to have around if you have acreage. Our peacocks let us know when strangers enter the property. They'll even tackle snakes if they run across them.
It is very hard to raise them. The attrition rate is high. The first year our female peacock laid her eggs but didn't want to sit on them. We put them under our sitting hen but none made it.
The following year we put the eggs under a sitting turkey hen and we had wonderful results.
This year, again, with the turkey hen we have one peacock chick and are awaiting for the others to hatch.
If you live close to neighbors they may not appreciate the loud noises that peacocks can make. They sound like loud snorting horns, followed by loud screaches.
If you clip a couple of wing feathers they'll stay within your enclosed yard. They can fly high and fast without clipped wings.
If you get an adult bird, keep it inside its coop for a least three weeks and then you can let it outside during the days, but it must be inside at night due to night critters that cotton to domestic poultry for their dinners.
Any specific questions? Let me know.
