I had what I thought was sour crop in a hen, after about 10 days in the house with yeast treatment, probiotics, and massages the nasty foul smell combined with gurgling subsided. Never stopped eating and drinking and crop was emptying. Was about ready to add her back to the flock when I felt a very hard area just below her vent, felt like a huge egg. Internal palpation was not definite, she was pooping LOTS and it smelled to high heaven. So I started her on warm baths with Epsom salts, belly massages and high calcium supplements , stool softener and camelina oil. Another 5 days went by and she started to go downhill, mass was still there, still pooping. She stopped eating and soon passed away. Stumped, I necropsied her and found this, from her vent all the way up. It's very solid and rubbery and was one big ball the length of her entire tract. I broke it up to see what was inside. I was shocked to say the least. Opinions? Was this a "lash" egg or what the heck?? Sure has the looks of a lash egg, it was HUGE and filled her entire little self up. She was a Tractor Supply Sapphire Gem and was just over 2 years old. Her name was Splash and I will miss her.
