I have a 4 day old Rhode Island Red rooster chick, bred by my boyfriend and given to me as a gift to rear as my pet. I've noticed that when I pick him up and hold him in my hand, he settles down, shuts his eyes and will cheep calmly. But he also makes clicking noises with his beak (by opening and closing his beak quickly, it's definitely not coming from his respiratory system.) I just wanted to know if anyone could tell me what the clicking noises mean? Is it a behavioural thing - portraying happiness (like my hares will 'purr' when I stroke their heads by grinding their teeth as this is a behavioural noise to portray happiness and comfort) or a fear thing? Or is there some sort of problem with him? I don't think there is, butI really hope not Thanks in advance!
