While a usually get one egg a day from each of my 5 hens, I’ve been only getting 3 recently. I thought it was just because it was getting colder, even though their egg Laying wasn’t affected last winter but I’m worried something may be wrong. I found this is their nesting boxes today (see picture) and I don’t know what to do, is it that she’s not getting enough calcium? I always make sure they have some in their feed. Any help would be awesome to get my girls laying again and make sure their all healthy
