Are you sure you want to eat something you have no clue why it died? I never process mystery deaths. I either bury them if I really liked the chicken or throw it in the garbage to be eatten by wildlife at the land fill.
Re: her stiffness. It takes 3 days for rigor to release, so if you are going to process her, into the fridge for 3 days, then she will be more plyable.
IF I know the bird was healthy yesterday and it died today I have butchered and eaten them. ESPECIALLY in the 9 to 10 month old range as this is when natural birth defect show up and kill the bird. Every time I have butchered a bird like in this case the heart was soft and surrounded by blood. Heart attack. I have noticed through the years of keeping far too many chickens that when a chicken dies at 9 to 10 months old, it was due to a birth defect that comes to a head at this age. I compare my theory to humans born with a heart problem who most always need their heart fixed in their early 20's.Thats what I was thinking, but I don't know much about eating processed birds yet - ones that were alive or already dead! So I thought maybe you guys knew something I didn't...LOL
I probably have shared this theory on this thread before. I certainly have shared it on BYC and other places. When I guess that someones dead hen or rooster is 9 to 10 months old ....and am right.

Can't learn that in some stupid book
