Thank you. Gal, but that's OK. I always think it's fun to guess posters' gender.
Yes soil will work well to provide some grit, usually. Only if it is pesticide and herbicide free though. Good old dirt is great enrichment. They might be nervous at first, give her time. If you can, post a pic. At 8 weeks we might be able to tell gender.
That document looks pretty detailed and probably accurate... though I don't know if it included everything. What kind of farm stores or pet stores do you have? Can Amazon deliver poultry nutri drench to you?
Scrambled egg will have selenium and other key nutrients available. It (yolk) has everything to sustain chicks for their first few days of life. In extreme cases I will dose straight yolk, but usually only from my own flock as it comes with it's own set of risks. But even cooked should be pretty good if you pique her interest.
8 weeks old? I think 18-22% protein is good depending on breed type. Again some needs to come from animal source, chickens are omnivores and will eat bugs and worms. If your oats are whole, you might even be able to sprout them (whole different thing).... Are you planning to keep the chick indoors long term or eventually move it out? What kind of treat have you been feeding? Did you use heat while the chick was getting feathers? How is the crop feeling? Is it full at night and empty in the morning? Does the chick have light all night?
I didn't mean to indicate that you chick wasn't lonely or depressed. It may well be part of it, just not the root. Any time I had a single chick they would raise cane for me to stay with them. But I know each will be individual. Where does this chick stay? Will you be keeping it if it's a rooster?
You may be able to use human supplements, it will just take a little figuring. I'm no expert at all... but will try to help looking into it.
