Does the comb of chicken have anything to do with whether they are laying or not?

No, the comb of a chicken doesn't directly indicate whether they are laying eggs or not.

Here's why:

* The comb is a secondary sexual characteristic: It's mainly related to the chicken's hormones and overall health, not directly to egg production.

* Comb size and color can fluctuate: A hen's comb may get bigger and more vibrant during certain times of the year, especially during breeding season, but this isn't a reliable indicator of egg laying.

* Other factors determine egg production: Factors like age, breed, nutrition, and overall health play a bigger role in whether a hen is laying eggs.

However, a healthy, vibrant comb can be a sign of a healthy hen, which is more likely to be laying eggs.

So, while the comb doesn't directly tell you if a chicken is laying, it can be a general indicator of their overall health and well-being.
