There is no nutritional difference between a non fertilized egg and a fertile egg.
You will not see a difference either as the germinal disk is so small it is almost invisible.
Most farms with small flocks have a rooster among the hens and they sell the freshest eggs you will ever eat.
No. A chicken can produce eggs without a rooster but she can not produce a chick without her eggs being fertilized by a rooster.
A chicken can, yes.
To get non-fertile eggs you need to keep the hen and rooster separated, or get rid of your rooster all together.
No rooster can lay eggs.
NO. Unless the chicken has mated with a rooster, she will lay non viable eggs. An egg will be produced by the chicken even when no rooster is available. Eggs that come from a grocery store are not fertile and therefore can never produce a chick.
A female has a little bit of feathers on its head and a male doesn't. Also, a rooster (male chicken) crows; a chicken clucks, and a rooster fertilizes eggs, whereas a chicken or hen (female chicken) lays eggs.
No. The egg won't be fertilized and it will be a yolk. But then again, if you want scrambled eggs, then i guess you can have it without the rooster.
No, hens will lay wether they be with a rooster or not
They lay eggs daily, but if you want chicks you have to have a male to fertilize the eggs.
They are sexual since a rooster is needed to fertilize the eggs.
a rooster has to make love to them
Only if the hens are in contact with, and mating with a rooster. Even then though, if the rooster is infertile for whatever reason, the eggs won't be fertile. Also you can tell if you crack them open and there is a small red dot in the middle of the yolk.
