I found tiny chicken eggs (approx the size of a penny!!!) in my yard. The oldest of my chicks that hatched this year are about 4 mos old, and are a cross between sizzle/silkie and millie fluer. Could these be from them?? I have never had a hen start laying prior to 6-7 mos.... Not really concerned. Just curious Anyone else have this experience? Fairy eggs perhaps, from what I've read?
