It is odd that Big Fatty's disposition has changed since the implant. It has been helpful that you have been keeping an eye on her and are aware of these changes. Maybe the vet would have some input as to what may be causing this. For the last few days, Ellie has been super hyper - much like her days as a young chick. Last night, I noticed that her comb was plump and flopped over again and was a bit concerned that she was once again on the decline. She seems more subdued today and not as perky. Her comb is very warm to the touch and she is holding her tail straight out. Right now, she is standing and shivering a little. I am thinking that she may have an egg forming in her system. It really knocks her out. I can always tell when she's getting ready to lay. I hope that she will be ok and that we don't have another emergency visit to the vet during the weekend. 
I'd love to stay in touch! Keep me updated with Big Fatty's progress! She seems to have quite the personality! I loved reading about her antics!
