Hi Socks,
It's hard to tell from your photo but do they look like this?

I'd guess from the photo that it is some sort of fungus. Egg capsules are larger than bird seed.

Jasdip, what a great shot. I'll take a close look when I go out later. Thanks.

That is really a great picture jasdip! Susan, the "eggs" as you call them are actually casings or capsules that contain the true eggs and sperm from the hermaphrodite mating of two worms - it's a really weird process. Several babies develope inside each casing. For a good explanation look up "cocoons" in the worm dictionary.
