Lots of small centipedes in raised bed

I’m in zone 8B and I was tilling it again today and got lots of these.  
I should have let the chickens do their thing
Or are these ok?  

I believe that's a millipede.  Sometimes they're a beneficial part of soil life.  Sometimes they snack on seedlings.  I usually just view them as a good sign of healthy soil biology.

I agree, looks like a millipede. I haven't had any issues with them. I usually see them going after already decaying matter, so I figure they're helping.
My chickens only eat them as a last resort. Millipedes can produce a nasty smell to ward off predators and I think that discouraged them. Perhaps wild birds or some other critters will eat them?

How many legs are there per segment? One leg (per side!) is a centipede, 2 legs is a millipede. I think (I'm certainly no expert) that either is a good sign. I wouldn't try to eradicate either.
