I live in a place with sandy soil, so I give them that. I also sift out the regular grit and give them the small pieces out of it after they are a couple of weeks old. I don't buy the chick-specific grit.
Welcome to BYC and congrats on your new chicks!
Make sure to offer grit alongside any non-feed treats and to limit the amount of treats so that most of their diet is regular feed. I wait until 2-3 weeks old, but it's worth noting that very young chicks eat bugs/plants/etc. when they are raised...

Fortunately chickens usually heal well from flesh wounds! I would clean and disinfect with chlorhexidine regularly rather than wrapping, which can cause entanglement and keep her out of beak's reach of the other chickens until it dries up and looks less tempting for them to pick at. You may be...
I'm sorry your family member was scammed, these look like someone's older production hens. Definitely quarantine them away from any other birds you may have. It might be tricky to figure out what is wrong with these hens. It could be disease, or it may just be that they were kept in very poor...

I agree that he looks like a barred Plymouth rock. The fact that he's a cockerel will become increasingly clear with time; the option to switch for a pullet is nice!
