I'm with Rancher. Silkies are not real chickens, they are hatching machines. I had one go broody in the sand in the bottom of my coop, sitting on NOTHING but the nest she made in the sand. I let her hatch eggs ON THE FLOOR...she didn't care, she just sat there for 28 days (hey, didn't say they were GOOD Eggs) and got ONE chick for her efforts....poor chicky momma....
I do wish she would start laying again...Heck I wish ANYONE would start laying again....but I do miss her light tan/pinkish eggs daily. She was my most reliable layer before she went broody.
This is because she was triggered by the mother planet and they didn't know she didn't have eggs to sit on. It's a crap shoot from their perspective. They expect all silky hens to lay a bunch of eggs and then they hit the "brood button" which is connected to a micro chip in her brain. Make sure you have your tin foil hat on when you are near them. Okay?
