Granny
We have an old hen.She's the last of the original three - her and the Grandpa - the big boss of the greenhouse. He's not showing his age at all, but Granny is obvious.She's tiny, she moves slow, she's not very white anymore, her head tips forward, no one bosses her, and her poof of hair feathers overhangs her eyes in a way that makes her look wizened.
She is the progenitor of half of all the Silkies in the greenhouse, but I think her hatching days are over. Every morning she eats with gusto but then toddles back to the coop, hops on the ramp, and goes back to bed. One of these days she won't wake up in the morning.
