I found a secret nest in my shed on Wed. It had about 6 eggs in it. I went away for the holidays and now there are 15 eggs in it. The eggs are coming from three-four different hens. One hen sits on it at night, but abandons it all day. I removed the brown eggs and left the six blue eggs (so I can tell when a brown egg is new). Should I toss the brown eggs? Eat them? I candled them (very porous) and floated them (sank with a little bobbing). I hate to waste them if they are usable. What do y'all think?
