Had a racc00n get a chick

Hey all,
I had a raccoon get one of my chicks and the hens have stopped laying, one of the hens now roosts in a tree nearby.

The night the coon came there were partly developed egg shells on the floor of the coop (aborted eggs?).... today there were the same.

I have never seen this before. Is this common? Am I on crack and those things are some fungus?

Any help would be appriciated.

Scott

p.s. the coon is no longer a problem, though we are keeping a trap out nightly.
