No they do not. If they did it would be very easy to separate the future roosters from the future hens.
Chicks get nourishment before they hatch from the egg from the egg white and the yolk, which is absorbed into the chick's stomach just prior to hatching.
The main difference is in the strains from which the roosters came. Hatch and Kelso roosters are also colored very differently.
Chicks can hatch from any egg, conventional or organic, if the egg has been fertilized by a rooster mating with the hen that laid the egg. Most eggs sold in retail stores are from flocks that include only hens and no roosters, so if you do not know where an individual egg came from, the chances are great that that egg will be infertile and not hatch.
You need roosters to fertilize the eggs, therefore producing more chicks.
they can hatch at anytime trust me i had my chicks hatch when i just started goin to bed
The difference is that precocial chicks are relatively mobile as soon as they hatch. Altricial chicks require heavy nourishment and care before they mature.
yes
If the hen has chicks it will be aggressive towards you or roosters are dangerous towards other male roosters.
Roosters don't lay eggs. Hens do.
Yes. When kiwi chicks hatch, they are fully feathered and well-developed.
chicks could come from both roosters as the hen stores sperm and releases it drop by drop as each egg is ready for fertilisation
