Who is laying the eggs?

[Sgsf]

Yeah! I finally got chickens laying eggs every other day now. It's currently only one chicken, but I'm not sure who is laying the eggs. I'm in school when it happens, or asleep. The eggs are very small compared to eggs you buy at the market, and they are medium brown colored eggs. (dark + light brown colored egg)

I'm not sure if it's the Black Cochin Bantam, or if it's one of my Silkies. Who is it?

Congrats! I bet it's the cochin, from what I understand silkies are really slow to mature.
