Are any breeders of Legbar noticing a genetic weakness in these birds? Mine seems to be having respitory issues and this has been going on for weeks. For months she has been doing the head shaking, which I assumed was because her extra large comb or crest was tickling or bothering her. But I've realized she does not breathe the same way as the other chickens. She does a lot of open mouth breathing as well as sounds congested. Again, this has been happening for months. I was wondering if it could be her heart? There is absolutely no discharge from her eyes or nostrils. No one else in the flock is displaying these symptoms. I have always felt she was a little "behind" the others, and now I'm starting to worry. She is 8 months old and still not laying.
I believe her egg came from Greenfire farms. Any insight to her behavior would be appreciated.
