i am soooooo sorry ZooMummzy! What a sad thing finding your girl like that. But i have to thank you for having the necropsy and letting us all know the results. i am guilty of giving my girls tons of treats. Lately it has been a lot of angel hair pasta, since they love it and it looks like worms. Guess i need to cut back on that.
Please don't beat yourself up about it. It very well may be that Alice had a predisposition to obesity, like Lunachick said. You clearly are a good chicken mom, and now you've taught us all how to be better moms. i hope Alice is happy, pecking around in Chicken Heaven.
