One of our chicks who is 3 weeks old is driving our family and the other chicks crazy. She rarely sleeps and she paces badk and forth in the cage and chirps VERY loudly. She stops if I hold her and wrap her in a washcloth and carry her around with me. She falls asleep immedicately. She seems so sleep deprived and nervious. I think the other chicks think she is crazy. I recently divided our chkcs into 2 cages of 2 each. She seemed happier at first...and is now back to pacing. Any ideas?
