Silkies being odd.

I had a persistent little guest in  the layer coop the other day.  I was cleaning it out - bagging up the thick accumulated layer of hay and crap for relocation to the garden (my chicken mulch cycle), and along came Granny.I lifted her out a couple of times, because she was definitely in the way, but she came right back in.  She was determined to do something, but it wasn't clear what.  She just sort of dottered around, and I had to relocate her to work around her.  I think she might be losing her vision.Ahhhh. I stay here now.Then, for more bizarre behavior, along came a Silkie rooster, who got all worked up scratching and wiggling down in the clean hay in a corner, gurgling and clucking for all the world like a hen that's very pleased with finding an awesome place to lay an egg.  He was just giddy with his burrowing.  WTH?  There's hay all over to wriggle in.  He was really excited about this corner, though.What a weirdo!
