But yours looks like a thing of beauty, mine looks like a bunch of stuff I got cheap from the HW Mega Store to slap together with rivets and cable ties (well it is roughed in only at this stage). This is really version 3. I've found that the trick with a Chicken Coop is that it is about keeping stuff OUT (it is very easy to keep the chooks)...
Ver1: Made a Pen (say 100 square mts) use using Bird Netting = Chooks stayed in, 2m Red Belly Black Snake got tangled in the netting, Neighbours Dog ran right though it and was using one of the Chickens as an popsicle.
Ver2: Upgraded the Pen using Chicken Wire and Nailed the bottom to planking = Chooks stayed in, Bush Turkeys would fly in. Also we seem to be attracting a Fox (can smell it) but it has not made a move yet
Ver3: Chook Tractor. Much smaller but is enclosed on 5 sides (bottom open) is under constructure and we have 2 of the Chooks in there to "test" it out before I "finish" it off.
PS both the snakes and bush turkeys get to live (protected species otherwise ...... Ver3 may not have been needed).
