I have 8 bantam cochin and Porcelain D'Uccle chicks that I hatched under a broody hen five days ago. Everybody has been doing fine until this afternoon when I noticed that one of the cochins was cheeping excessively and turning in circles. She turns about five or six times then stops and her head turns left to right a few times and she stops. Then the whole thing starts all over again. I picked her up and carried her around with me for an hour or so and she seemed totally normal and snuggled into my hands and settled down. I have the momma hen and the chicks in a separate coop from my other hens with pine shavings as bedding. They are eating a starter crumble and have constant access to clean water. Does anyone have any idea what might be wrong? I have a bunch of other chicks of various ages and laying hens and nobody else had exhibited any problems or any behavior similar to this. I read something about a nutrient deficiency in selenium and vitamin E or possibly an allergy to the bedding. Please help! I'm so scared I'm going to lose this little one! By the way, she/he is the chick darker chick with the medium gold head in the pics.
