So how do chickens hear with none exterior ears?
Like people, chickens have an eardrum, an ear canal, and a cochlea.
Chickens can detect frequencies between 2,000 Hz and 4,000 Hz, which permits them to listen to sounds we can not.
This implies they higher sense of listening to than people, and their listening to is best when the sound comes from the entrance.
Rooster ears are additionally delicate to modifications in air strain, they usually use this to detect modifications in climate.

Chickens with this gene have blue earlobes, indicating their means to put blue or inexperienced eggs, whereas chickens with out have white earlobes and lay white eggs.
Brown eggs, nevertheless, is a little more sophisticated as a result of they’re related to a number of genes and are linked to a rooster’s purple earlobes.
However once more, there are at all times exceptions to this rule, just like the Easter Egger (purple earlobe, blue or inexperienced eggs) or the Ameraucana (purple earlobe, blue eggs.)

Hens that lay white eggs usually weigh much less and are extra environment friendly in feed conversion than people who lay coloured eggs.
Brown eggs are additionally fairly frequent, making up about 10% of all eggs offered in america.

Some breeders might desire brown eggs for his or her bigger measurement or as a result of they imagine they’re more healthy, however in actuality, the dietary worth of brown and white eggs is just about the identical.

Consequently, when these genes are handed all the way down to a rooster, they have a tendency to stay collectively.
When a rooster inherits the dominant pea comb gene, it additionally has the next likelihood of inheriting the blue egg gene as a result of they’re each dominant traits.
So, sure, chickens with pea combs usually tend to lay blue eggs.
Nevertheless, it’s essential to notice that the pea comb gene and the blue egg gene are two completely different genes, so that they don’t at all times come collectively.
If you wish to breed chickens for white eggs or single comb crosses, it will probably take extra time as a result of it entails mating pure breeds.
Nevertheless, this doesn’t imply that these traits are inconceivable to attain – it simply requires a extra selective breeding course of.
Some rooster breeds usually tend to have pea combs and lay blue eggs than others.
