I know it is impossible to tell a roo this early in the chick game, but, my 6day old chipmunk striped chickie ( still have no idea what it is, lol) did this weird chirp earlier. Like three times in a row. First it was a "chirp peep peep" like usual, but then it stretched super tall and did a "whirrrrrrl" imagine kinda like a police whistle? I dunno, it is hard to explain and I couldn't get it on tape. What kind of noise is that? Is that normal? Also, they seem more skittish today of me than they have been, but still all fall asleep when I hold them. So do they go through fear stages like dogs do? Thanks in advance for any help!
