Looks like a really nice set up Mike. I wonder if there's any way that you could incorporate a scale in there to weigh them while you're running them through. Don't know that it's necessary, but figured it was worth asking...
The folks we bought this from have a scale that becomes integral to the tilt table but they are proud of those things. We have a scale on order that will fit inside the chute and we have a way to keep them from backing up so we hope that will work.
We drove T-posts around several trees that we had planted in the pasture to put fence around them and also two patches of Giant Bamboo that we planted last year. Once the bamboo gets established the sheep will eat anything that gets out of the fence and they do really like it.
We are incubating some duck eggs for our neighbor and we will keep a few. I didn't want ducks but Teresa does so now I do want ducks.
I will share what I have learned with ya. In building an area for them, just think more of a baseball "Dugout". They really don't need anything elaborate, and ya want it easy to clean. They will trash any water they can reach, so keep others water higher than they can reach. Chickens will climb up, ducks won't. This will help ya to not want to deal with them, and the Eggs are wonderful, especially in baked goods...
Nobody has any idea what kind they are. I'm not big on ducks but Teresa wanted them so we will try hatching ducks. Nothing to lose and the home they are coming from has a big pond and will take them back if we decide we don't want them. This is a neighbor whose High School son has been working for us and he is the one with all the poultry.
