My chicks are just now 4 days old (this is our first time with chickens). I've noticed over just the last day that the chicks seem much more easily startled than they did the first few days. Whenever we enter the room or peer over the brooder box to watch them they will jump and/or scatter, pretty much all of them. After a few moments they'll settle down unless we make a quick movement or unexpected noise. They'll also scatter whenever we reach into the brooder to replace feed/water/bedding or if we need to pick one up to deal with a pasty butt. Now, all of that seems pretty natural to me. It's a natural instinct for them to be wary. My question is, can me and my wife do anything to help mitigate that impulse and acclimate them better to our presence? I don't want to be giving my chicks a near heart attack everytime I want to check up on them, plus I assume down the road it would be beneficial if they don't scatter when we come near. I've avoided handling them as much as possible, only really touching them when dealing with pasty butts, so as to avoid the stress/possible injuries of doing so. Should I be handling them any more to get them used to me? If so, at what age should I do that (maybe a bit older so they aren't as fragile/injury prone)?
