Okay, I know daddy is my white silkie rooster, however I've got 4 different hens in with him that all happen to lay the same color/size eggs!!! No clue who mommy might be, any ideas? The contestants are: blue cochin, black cochin, golden comet, and my really old RIR who I've only caught recently laying an egg. She showed up a couple years ago, just wandered in, idk her real age, but I'd guess at least 6 or so... By coloring i'm guessing the RIR, but...???
