So I recently bought 6 Easter egger chicks from Cackle hatchery and they're about a week old now. I noticed they get very skittish when I put my hand into the brooder to change the water or their food. This all changes when I let them run around on the floor, they approach me with no fear to "investigate" I could even pet them and grab them without them running for cover. So what's the problem? Is this normal? Has anyone dealt with this before??
