Irish, I do think it is possible they are molting. I seem to have feathers EVERYWHERE. And a mild drop in production. Although I do have yet another broody.
But I think yes Dannyboy could be eating them gone. When I make eggs, I scramble a little bit extra and add in the shells. It is good protein. I feed it to the chickies. They eat the shell completely gone. Danny has no reason to go in there. Rae never goes in ours.
If I were you, id direct that camera right at the nesting boxes to find the culprit.
Good luck!!
I'm thinking it might be a combination of molting - two or three of them seem to be into it right now - and that sneaky roo! I'm surprised that there is absolutely no evidence of the crime. Of course, I haven't gone in and thoroughly checked all the straw, but I would have thought there would be something he/they missed.
I may move the tractor closer to the window so I can see inside better with the chicken cam.
Between the chickens and the critters in the garden a person could starve here if they were dependent on the raising of food. It looks like the bunnies
