Her feathers have been looking like crap lately and I've seen some blowing around the yard... but I've only had these chickens since the Spring so I don't know what a molt looks like. They're probably about the right age though- about 8 months old I think.
I have 3 other hens and they all get layer pellets with some ridiculously high protein percentage (22%??) because that's what the guy at the feed store sold my boyfriend. They get some scratch and BOSS for treats, as well as the odd vegetable or boiled-down chicken carcass to peck clean. (That's a whole 'nother post.)
They "free range" in our tiny yard when someone is around to protect the garden, and they mostly just go for grubs in the mulch around the trees and in the compost pile.
It has been really hot lately (100 today) and I would think that would slow 'em down, but the others haven't really. Plus she's a Spanish breed so she should be able to take the heat!
