I am at a complete loss....we have 2 girl chickens and 2 girl ducks who have been giving us eggs for weeks. Last weekend we got this tiny egg and then again today 2 normals eggs and a tiny egg (don't get duck eggs everyday so assuming it's a tiny chicke. Egg) but how...why? How are we getting 3 eggs from 2 chickens and why is it so small? It's also more of a brown tint where ALL the other eggs are blue green?
