I have all sorts of chickens. I've noticed the following with ours:
Sex links - doesn't matter what kind - most likely to nip at me when I'm gathering eggs.
Rhode Island Reds/New Hampshire Reds - most likely to be the guilty party whenever I find eggs with holes in them or eaten eggs. They even attack the basket as I walk to the house.
Now, as for ordering from a hatchery.... I decided to put in another order this past weekend and was disappointed at the varieties available almost anywhere. I have a feeling that heads rolled at MM - they don't have all the breeds offered as in the past - just look at that availability chart!
I decided to wait a while to see if things get back to normal in a few weeks. I've ordered when the pickings were slim before (from Ideal) and I'm still not happy with the results. Seems like when the hatchery has more for them to choose from, you get better looking chicks and not just what they had handy.
