Any chicken can lay a small egg, really at any time. Sometimes, a chicken will lay a very small or very large egg as a "ladder egg", going up or down the laying cycle. So the color says silkie, but the size doesn't matter!!
Thanks. I have a new Cochin bantam, and two reds. One of which has squatted since the day I got them. She's a massive chicken. Just wouldn't have thought she would lay such a small one am especially in the middle of my back yard.
So I'm still not sure who's laying the small eggs but they're not laying them in a box. 2 were fond in the middle of the yard so I kept them I. The coop for a couple days. Each day I've walked out and found a small egg on the floor in the middle of the coop. Any ideas to get them to lay in a nest box. I've got golf balls in both boxes. 2 boxes for 6 chickens. Only 3 laying.
