I am new here and new to having chickens. We have 12 young chicks (well, they're probably about 2 months old now, I guess....) and when myself and my two young sons went out to check on them tonight (it would have been early evening, about 7:30 pm), the chicks seemed very friendly toward us. We got them when they were about 2 weeks old and we didn't handle them a whole lot, just a little here and there. So it surprised me at how friendly they seemed tonight. They really seemed to hover around us and one actually jumped up on my son's lap and sat there for quite a while before hopping to his shoulder and then made a nice little spot on the back of his neck to sit. It was funny and weird at the same time to have them be that way toward us. A little while later, another one hopped up on my leg and then another, then I held my arm out straight to see what they would do and they both hopped up on my arm. Is this ok to let them do this to us? Is there some sort of "bird psychology" I should know about? Will they "think" they have the "upper hand" with us? lol I feel strange asking these questions, but I don't want to encourage behavior that is going to bite us in the butt at a later date. Please advise! Thank you in advance.
