Thanks, everyone for the feed suggestions. I appreciate all the feedback. I will add to their diet keeping in mind the fat content. My chickens are healthy - laying eggs regularly, have nice looking feathers, bright eyes and active, and were wormed in October. No mites, lice or anything like that. I check them often for that. Maybe I'm just overly concerned. They're not skinny, just not as plump as I think/thought they should be.
Now, I'm still working on getting them to go into their coops at night. Lights are on in both, but had to put them in there again tonight. I'm running out of patience with that, and am tempted to just let them roost where they will. There isn't electricity to the coops and the batteries run out pretty quickly in those light fixtures I hung in there. Batteries are expensive. I really don't like the idea of running extension cords across the yard. Fire is a deterrent.
BetsyOK - congrats on the hatches!
