Eggs will be a useful and economical byproduct of pasture sanitation. The chickens will follow the cow rotation on a 5 day delay to allow fly eggs to be laid and hatched in the cow manure. In order to get to their nutritious meal, the chickens will scratch and fling the manure. First this process distributes the manure so the cows can re-graze the entire paddock upon pasture regeneration. The nutrients in the manure are broadcast so they build soil more evenly opposed to inundating patches with the acute manure piles. Lastly, the scattering of manure helps to break and prevent pathogen growth cycles.
My mobile chicken house will provide water, shade during the day and predator protection at night when the chickens are enclosed within. Half inch, 19 gauge hardware cloth will let excrement fall through further fertilizing the pasture while keeping snakes and predators out. Water will be provided via an old 6.5 gallon bottling bucket retired from brewing beer. Via gravity, a short length of hose will feed water to nipples on a pvc pipe. The nesting boxes will be accessible from the outside for easy egg retrieval.
I have not decided on a trailer base for the henmobile, so I put it on a generic 4×8 utility trailer for reference. There are no structural considerations in my model yet. Without further ado, here is the hen mobile modelled in Sketchup!
