So this is what I encountered when I walked into my coop today. I have two rouen hens and with a drake, a silkie hen with a rooster, and four laying hens. Three of those laying hens are pullets. I am trying to figure out whose eggs are whose. I assume the small brown egg is either my silkies' or could it be my pullets? And do rouen ducks lay blue eggs like in the picture. So far none of the birds are sitting on the eggs. I know I could collect and eat all of the eggs, but I am hoping my silkie or ducks will start sitting on eggs and I don't want to collect the wrong ones and screw everything up! haha Thanks for any help, I am new to this whole bird thing! Here is a close up of the mystery small brown egg and my laying hen's normal egg.
