Is it normal for a 5-day old chick to be trying to fly out of the brooder? It is about 16 inches high and of our four chicks, one is trying desperately to fly out and has been almost successful several times. I think it may be a rooster, he’s a real jerk.. We only have these chicks for a few more days as it was part of a homeschool chick hatching experience. Is there anything I can put over the top of the bin of prevent mr smarty pants from escaping?
