I have a pair of pea fowl. They like to wander the property, but have taken to our neighbor's property as well. I realize I need to pen them. What do I need to provide for them in the pen? They roost in our 3 sided barn. I think I would like to enclose the 4th wall with chicken wire, so they could still roost there, but would be outside and sheltered. Any ideas? I don't want to sell them. Mr. Pea is just starting to get his eye feathers.
