[TheForge] OT - Quesyion about a nest

[Jerry Smith]

Folks,

This morning I was clearing my barns over hang of wood
and other such stuff.

I found a nest under the wood, about 10 inches deep,
by 18 inches wide. Lined with straw, hay and twigs.

This was under a bunch of wood.

What critter made this nest?

Thanks,

Jerry
