I have Golden comets that are 2 1/2 years old. One of them has always had an excessively large craw - so big & wobbly that we named her Mrs Jiggles when she was just 6 or 8 months old. Well Mrs J has developed a strange neck twitch - my kids said before Christmas but I've only recently noticed how bad it's got. She kind of does this neck wiggle/ dance, and it looks very uncomfortable. She'll do it for a few minutes then stop and eat. When she does it, it looks like she has a swelling on the side of her neck, but I can't feel a lump there. has anyone seen anything like this? I am not sure if it's related to her excessive craw, wondering if she has been eating gravel over time or something & is now struggling to swallow? though her crop area isn't hard. Most of the time they are in a run but a few evenings each week they are let out around our yard and in the woods. Any ideas?
