First timer hatching chicks. This chick (don't know breed) was hatched at 10a.m. today. At first there was a sack like thing hanging from it's belly button. Looked like an yoksac. Noticed it was getting longer as time went on. Then noticed what looks like intestines hanging out. I cut what I think was the yoks sac attached to the intestines. Chick is active but not sure what activity level should be. Please help.
