They do if they are fertilized by a rooster. There are many many cross breeds on farms all over the world. As long as the species is the same the rooster will mate with it and a hybrid is still equipped with an egg producing oviduct.
After mating.
None. Roosters do not lay eggs, because they are males. They do, however, fertilize hens, who then lay eggs that can be either fertile or non-fertile.
As long as there is no rooster around to mate with the hens, you will not receive fertile eggs.
All hens lay eggs.
No, only if you want fertile eggs. The hens will lay without a rooster.
Hens are mom chickens and roosters are dad chickens. Only mom chickens, hens, lay eggs. They lay eggs all year.
There is no such thing as a "boy hen". Hens are female chickens.
It depends on what breed of chicken it is - normal laying hens lay about 150-200 eggs a year, but chickens like bantams and ornamental breeds lay about 80-120 eggs a year. Hybrid hens lay about 300 eggs a year! The record for most eggs laid in a year is 364. A day off for christmas?
Hens lay eggs, the ones you eat.
Yes, hens can lay eggs for 2-3 years.
Feather coloring does not influence the color of the egg laid. The breed of the hen dictates what color her eggs will be.
Older birds do not lay peewee eggs. Young hens and smaller breeds of hens lay the peewee eggs and the older the hen, the larger the eggs are. Hens tend to lay more eggs in the spring and summer.
