On the earthworms...
I've noticed, too, that sometimes my birds will eat them freely and sometimes not. I had read somewhere that they can carry various things (without going into detail) that would not be great for chickens and that the birds are able to tell the difference and will avoid worms that may not be good for them to eat.
Maybe that's why there is such a variety of response to the worms.... one day mine will go after them and then the nest they will take a look at some (usually in different areas) and not touch them at all after they get a good look.
