So, about a month ago- one of my hen's was eggbound. My husband and I took all of the neccesary steps, and we "saved" her, and she passed a soft-shelled egg that night. Last night, I went to the coop to collect the eggs and saw she had laid an egg. I always count my chickens before I lock them up inside completely, and last night I was missing one. She was laying in the bushes by herself, so I brought her inside. She was acting like she was eggbound, but she had already laid for the day. However, I took all of the neccesary steps once again, and gave her some anti-biotics, poly-vi-sol, vitamin d, and calcium. I woke up this morning, and she passed a soft shelled egg. Is this normal? Does this happen sometimes? Or is there something "wrong" with her egg production? Is there anything I can do to prevent this? They are on layer pellets, and have access to oyster shell. They also free-range during the day.
