Crooky died

I feel so guilty. What if I'd drained the air bubble sooner. What if I checked on him more often. What if. Damn it, I wasn't even going to bother with any of this at first, and was prepared to cull and just be done with it, but once I started spending time and putting effort into it, I guess I bonded with the little thing. He made so much progress yesterday (he was walking!!!), I really thought he could come out of the crookedness and be a normal chicken! Maybe it was the air thing, or maybe he had other issues, who knows. I'm just so, so sad.
