My blue Cochin (her name is Shadow) only has one developed waddle. She is supposedly 9 months old. I got her in July from a breeder who stated she was 5 months old. No, she has not started laying and she show no signs of laying yet. Not squatting or checking out the laying box. She is very calm and seems to be on the bottom of the pecking order of a flock of 10 hens. I do not have any roosters. I have search the web and other forums and have not found anything on this. Anyone else seen this? Will the other waddle eventually catch up?
