Hi, Ebbie. check this out:

Also - please don't put manure in your raised bed. Manure spreads disease and parasites. Farmers spread manure on their fields to get rid of it, and sun, wind, and soil bacteria usually take care of its unhealthful effects.

But don't put it in a small bed in an urban area where children are going to handle it, explore it, and make mudpies. Yes, today's children still make mudpies. I saw some not too long ago, and they were as cute as could be.

If the bed is growing weeds and feral columbines, its soil is probably pretty good right now.
