Updating what I mean here. I've attached a link to a pheasant housing site that shows an ark
http://www.avianweb.com/housingpheasants.html
Unfortunately no plans or other info is included. It's obvious from the pic that it's 2/3 wood and a foot of wood at bottom of last 1/3 to try and keep them calm.
I've also seen a pic from a book on pheasants from a state agriculture site or University showing pheasants in movable pens that llok no bigger than 4X6. It notes that pens are small enough to be serviced from outside and eggs retreived with a tool.
I also found a site showing pictures of pheasant "battery" operations in Britain that show 1 rooster and 8 hen ringnecks in a cage that's 4X6. The birds have nose rings and are hard on each other. I wouldn't do that as it is too cruel for these birds to be in such close confinement.
When I was young (age 13) I knew nothing about birds and kept a pair in a cage in the basement all winter. I remember the cage being not bigger than 3X4. The next winter I kept them in the barn in a space 4X3. They weren't happy but survived. (They got the run of the chicken pen in summer which was in the barn 8X14).
I need something that is collapsible or movable as I won't live here long (maybe 3 years).
I plan to build an ark 4X8. I can move it around to get eggs so no reason to go inside. Or I will build a nest box. They will get fresh ground daily. If it doesn't work, I can put netting around my shed but its fixed so no fresh greens.
Or how about the same ark with partridges? Thinking chukars.
Again any input appreciated.
