This seems to be a fad right now but I remember that chicken "excrement" is not a good smell. Fresh eggs are wonderful but that "excrement" also needs to be washed off of some of them. Some hens become protective and know how to peck a person--ouch! And nothing excites a person any more than reaching into a nest only to find a snake has decided eggs taste good. There are lots of predators that like chickens, too. Some folks are allergic to the feathers. Remember they sell eggs already cleaned and in a box at the grocery store--and right now they almost give them away in our area. I'll get mine there!
