What’s the best way to bond with chicks?
Mine are 4 days old, so I guess that I’m looking for ideas for now through the next few weeks?
Also, when can you introduce grit so they can try a treat?
They can have grit now if you want. Everyone seems to have differing opinions on it but I give them access to grit right away.
Best way to bond with them is just to spend time with them without trying to force them to interact with you. You can put your hand in the brooder (if possible, reach in from the side instead of from the top) and give them the option to come to your hand (that's where treats help) and talk softly to them. Or make a small corral where they won't wander off, and sit down with them and let them come check you out.
Does picking them up help? I assumed it would desensitize them eventually, but they act like they are being murdered every time.
Chickens in general don't love being picked up, and being grabbed from above makes them think they're being attacked, so that's why the chicks are running around upset. If you let them decide to jump up into your hand or on your leg, then they'll feel more comfortable with it.
