I would suggest you look at New Country Organics feed suppliers. I tried the organic mixing and realized that it's very expensive, time consuming, and hard to get a balanced nutritious feed for my chicks. Just ask Stormcrow. Good luck with your flock. NCO has fed my flock and they're very healthy.
You may want to reach out to @Wyorp Rock, an expert, to get more advice. You could mix a little of her food with a scrambled egg, just to entice her to eat. Sounds like you're doing all you can.
Is she still lethargic? You may want to isolate her so that you can keep a close eye on her. The warm epsom salts baths, even though she doesn't like them, may help her relax enough to pass the rest of the egg shell.
When I have transitioned feed types, I've been advised to mix the old and the new for about a week or two, just to get them acclimated to the new. Their tummies are sensitive.
Thanks so much. I want to be careful of their health, thus all the questions. Should there be any need for run fungal treatment, or replacing the pine chips?
After losing Lucy to Salpingitis, I have noticed that several of our hens have poopy butt, and the overall flock egg production is about half of what we usually get (5 - 8 eggs a day down from 9 - 12). Reading as much as I can from all of the experts here on BYC, it looks like salpingitis can't...
I don't argue either, that's why I've lived this long!:old We have a tendency to get too close to these babies. By the time one of those little chicks was found out to be a rooster, they'd be named, loved, and pampered - plus we would have a video archive of their first steps, first flight...
