I raise waterfowl. But am now adding chickens for show and stuff.(used to have them long ago). I want to build some chicken/ and duckling tractors using cattle panels probably (quick, strong) adding cage wire to them and adding either tarps as needed or house on one end built with light materials like vinyl siding for roofing or maybe some fiberglass panels, and want more than one as I could use then as grow out pens for the ducklings , and different breeds and separating excess males and females...thinking making cuts like a sled so it doesn't get hung up...I want to be able to pull it with my riding mowers (I often use them like a ATV my husband says) to move them as needed. Not on a daily basis, more seasonally. We have 11 acres with cattle fencing...but it is rolling. we have a lot of stuff on the flat area near our house, but to access other areas it is down a slope. I may get some electric netting later if I move them or other birds (geese) down the slopes.... don't want to use PVC pipes... we are in 60's , and although I was quite strong for a woman, I am now conserving heavy lifting to 50 lb feed bags...LOL... So I want to be able to slowly drag the tractor (with or without birds inside) and move it if I need too.Land has some rocks, roots etc. we have some driveable slopes...but there are predators in the area, and even with my fences, there are foxes, coyotes, hawks, raccoons...so I won't be using chickenwire... I probably will have some 'fence aprons' to add to the outsides to keep out diggers... I just wondered if anyone has made some that they can move this way? .(.. Our mowers regularly tow carts with dirt, rocks, logs, small trees being drug, so I know they can do some weight...) probably 4X8 or maybe up to 8X8....because I want to size them to use the cattle panels, which I may cut ...
