Maybe the hens need new bedding. I like freshly-laundered, air-dried sheets. Shouldn't they?
The nesting boxes are lined with wood shavings. Over time, the shavings collect dirt and crumble.
I spent Saturday afternoon cleaning out the chicken house and spreading new bedding on the floor and in the nesting box.
When finished, the chicken house smelled like a pine forest on a spring day.
The nesting boxes were filled with fluffy shavings, awaiting hens. Surely, they'd lay eggs now.
Again this morning, I locked the chickens in the hen house and checked it frequently.
By noon, there was no hen butt imprints in the freshly-fluffed nest boxes. I'm debating my next step.
