I completely understand your skepticism, and that "3" isn't that old, but chickens don't have near the lifespan as even dogs and cats unfortunately. I am not trying to be a negative Nancy, just being realistic and keeping things in perspective. I recently went through this with a very sweet 7 month old orpington, she started laying, all was well, then the soft eggs started, fixed that, then crop issues, fixed that, then they started again with a swollen belly...I did everything I could, antibiotics, calcium, coconut oil, stool softener, but sometimes something just isn't right in there.

@azygous , she knows her stuff! I hope your hen makes it with all my heart!
