My Delaware laid another shell less egg. She just started laying but both have been shell less. I know that some hens do this at the beginning, but how many should I expect before I get concerned? My RIR is laying small, but perfect eggs. She just started as well, so I don't think it's the feed (Layer plus free choice oyster shells), our water is well water and is tested frequently. Another thing is that she lays at night! She was singing away at 9pm last night. Sure enough at 7am when it's just barely light out, we checked...another wet mess. I think she must stomp on them or something! She seems perfectly happy and healthy. Sorta normal or should I add this to my worry wort check list?
