I recently started getting several small eggs along with my large ones. I have 10 week old cochin cross hens that have been in the coop for a few weeks (along with my year old hens). Is it possible for them to be laying so early? I would find it hard for my year olds to just start laying small eggs since they've been laying extra large for so long, but I can't explain it. Another possibility could be the older hens going through moult? do their egg sizes get smaller? I'm not sure if they are but some do have a few bare spots, not really a full on feather loss... hmmmm?
