Today I started my roul roul partridge pen build. The pen is going to be 8x8x7. Got in the main poles and the base today. Used 2"x16"x8' for the base birds and put 4" of them under ground. Inside the pen I'll be putting 1ft of sand for the birds. It is being built over a existing low light plant garden so during the summer it will be well planted which is what the birds love. Just picked up a 100ft roll of 1/2"x1/2" wire. I will be updating every day as I build on the pen. Any advice or suggestions feel free to give. As of now when the pen is done there will be a pair of roul roul partridge and a pair of zebra doves. Anyone have any finch suggestions?
