They are out enjoying the spring weather, scratching around, looking for greens, grains, bugs, and other chicken delights. Makes sense. That is what you expect from chickens.
What you may not be able to see in the photo is that they are scratching up a pile of "stuff" that was just shoveled out of the chicken house.
We use the deep litter method which essentially means we add bedding material (mostly shredded paper in our case) to the house floor. So there are layers of bedding, manure, and feed waste that piles up for awhile until we need to clean out the chicken house to fertilize the garden or the litter has simply just become too deep.
Today Kellen cleaned out part of the chicken house to prepare for chicks. So this litter has literally been sitting in the hen house for the entire winter. The hens have been content to walk on it and poop on it, but I have never seen them scratch through it in the hen house.
But shovel it into a bucket, and pile it near the garden, and suddenly it is a hot spot of hen scratching activity! There is no explanation.
And just because we all need a little cute in our day, I give you baby rabbits.
