Hey! My two year old Delaware hen has been laying extremely weird eggs lately. I have found smashed eggs in the coop with other eggs untouched that are in the same box. The egg shells are super thin and break almost upon contact. I always make sure they have oyster shells and they have feed with calcium in it already. This has been going on for a while. Her comb is still red so I don't know if this is a calcium deficiency thing or something else. Thanks!
