Their feed consumption has gone down quite a bit. They seem to be just amusing themselves and their tummies in the yard. Plus I give them wheat and barley and split peas and so on for snacks.
Still no eggs. Their feathers are ragged at the tips, but no real big losses yet. They look fluffy and healthy. It's weird to me that they all up and stopped laying at exactly the same time.
Add: Also, they are a lot more skittish and less personable. I used to be able to just pick at least one of them up and now they skitter away. They have stopped their mating squat behavior as well.
