KSALguy gave me some great advice on colony raising, as did others in the forum. Great bunch of people . I second the idea of going to the rabbits for profit forum here on HT. Do a search on "colony" and you'll get some great threads.
I'm on a colony raising yahoo group and many of them report the same problem with colonies....the rabbits are really difficult to keep tame enough to actually catch. (we're talking about outdoor colony here..theindoor ones seem to be more controllable)
The fencing.....Most suggest putting fencing down (some form of wire fence, or a solid thing) 2 feet so the rabbits won't dig out when they do their dens.
Another idea is to make the area huge....fencing in 1/4 acre or more...and put the feeding station in the middle. Putting it on piers. The rabbits will start building their dens UNDER the feeding station...and unless you go hog wild and have dozens of breeding rabbits...they won't go near the fences to dig.
I'm going to be doing 2 different colonies. 1 will be a fenced area, fencing into the ground 2feet down. pasture and woods combination area. Just 2 does and 1 buck. Meat rabbits. I feel it will work well,from the advice and stories I've been told. Central covered feeder...like a picnic shelter at the park

Water will be a 5gallon container feeding an automatic waterer.(dog bowl type) The fencing will be 2x4 welded wire, 5ft tall above ground, and with chicken wire 2ft high around the base to keep little guys in.
The second colony will be in a chicken cooop type building. with shelves for them to climb on...and a small door to the outside. When the door is opened, they'll be able to go out thru a tunnel into a covered fenced area. There will be 3 different fenced areas for them to browse. 1 each day...on a rotation...so that they don't graze any one area down to nothing. They will also get various raspberry and rose canes to munch on.
In addition to feed and the grasses, they will get hay. We'll see how it goes with them. Winter, of course, will be slightly different, with the outdoor colony getting more attention because of the water. Although, bunnies, like chickens, eat snow for water, so they can survive without running liquid water.
