I had 2 ceramic eggs in my laying box they disappeared then I was not getting as many eggs as normal. I have 5 production reds (Golden Comets) is what they appear to be and 4 black sex links all hens no roosters. Then 1 of my reds did not go in the coop one night she has not returned for 2 weeks never had a predator problem they are all about 6 months old and free range out at 7am in the coop at 8pm I have 3 acres with alot of hiding places for a hidden nest which we have sesrched for. After reading post I feel my red might have went broody with the ceramics missing and other eggs disappearing. Starting a couple of days ago we found a few eggs in weird places one in a bare area no seclusion at all another on top of the wire in there run not normal laying spots they use the nesting box to lay. This morning i let them out checked the box 2 eggs were there i left them there I was in a hurry my wife went out about 9 no eggs normally 4 by that time. No more eggs the rest of the day but all chickens accounted for except the red that has been gone for 2 weeks. They seem 2 young to go broody. But why would ceramic eggs disappear and others also. If the red went broody would she come back and steal more eggs for her clutch? We do have a few rat snakes around here. Any suggestions? We are new to chickens this is our first flock and love them.
