Your funnel shaped crowding area will work much better than the other design as animals do not like to come to a dead end and will balk at a 90* turn. I would possibly utilise the dead triangular corners by making them into jugs. Also I would add an additional "man" gate between the 2 pens at the point of the 2 chute gates ( extend the end board on the end of each gate sticking "up" to use as a handle) for better and easier operation for anyone operating the gates in the chute. I would also include an additional cross gate as a block in the chute for treating/ vaccinating/ etc. at the junction between the two swing gates and " man" gate to the pens. I would make the chute narrow enough so that sheep couldn't turn around when they come to a halt at the stop gate in the chute. Otherwise one may use expletive deleated language. Measure the width of one of the larger sheep (Keep in mind that a sheep in full wool will have a width about 4" larger than a shorn sheep will). If shorn add about 2-3" , if in full wool use that measurement ( one may add 1" but no more). The chute side walls should be about 6" taller that the sheeps' head. However just a note of caution... the problem that you may run into building the chute as side walls to the pens is the fact that when the sheep are in a pen and one works them or they get spooked, they may jump that short wall and into the chute. They may get caught on top of that short side, between the side and barn wall, land on their side or back in the chute and possibly injure themselves.bocephus said:I've looked at a bunch of designs and measured my pen. What if I build something like in the design I made below. Red lines are exterior walls, black lines I would make out of wood, blue lines are various gates. Not exactly drawn to scale, just a rough drawing. Each square represents one foot.
I end up with a chute running around the exterior with two pens in the middle.
