Okay, chicken peeps - the omniscient Internet says this could be multiple things going on with one of my girls. Have you had experience with this? For the last two weeks, my 1-year old chicken is regularly laying shell-less eggs that have a long, trailing white sac, and she's laying them everywhere (driveway, nesting boxes, roost, etc). The end of the sac is about 1/4" thick and hard like plastic. Her bottom is messy & stays messy, despite being cleaned by her mama (me). She and the other girls have unlimited access to oyster shells and 5 acres of Tennessee grazing land. How do I help her?
