I have three females and for the past two months I’ve only been getting two eggs a day when I was getting three. About a month ago I noticed a egg shell in the coop away from the nest with no yolk( they could have ate it) but the other day I found another egg shell laying in the yard (free range). I’ve checked all my girls nothing wrong with vents no one’s acting different nothings changed. Could one possibly be laying broken eggs? It’s only happened twice and I’m not getting three eggs a day like I used too. I’ve tired to see who isn’t laying on the camera in to coop but it’s hard because it just take pictures with the motion. Thoughts ? Should I just keep one inside at a time to see who’s laying to find the one that isn’t?
