Time hens continue to produce fertile eggs
If the rooster in a flock dies, or is removed, the hens will continue to produce fertile eggs for up to four weeks, depending on bird species. This is because there are "sperm nest" areas located in the oviduct of hens that collect and store semen for later fertilization of eggs. This is a natural survival mechanism for the production of a series of fertile hatching eggs even after the male is not available.
The period of time that fertile eggs can be produced without additional matings can extend to several weeks. If a rooster is removed from the flock and replaced by another, it may require 3 weeks before it can be assured that all eggs will produce chicks sired by the new rooster. The proportion of chicks sired by the new rooster will increase during this period, but some chicks sired by the old rooster may hatch. Birds like turkeys and waterfowl have longer periods during which fertile eggs can be produced without matings.
In a state where temperatures exceed 90 degrees more than 100 days a year, heat control in poultry houses is a very important consideration for Mississippi's biggest agricultural industry.
Poultry producers got off to a robust start in 2018, which helped the industry end the year strong.
STARKVILLE, Miss. -- More than a million backyard chicken flocks provide Americans with eggs, meat or companionship, a trend Mississippians embrace, but hobby farmers must learn proper care to keep them healthy.
RAYMOND, Miss. -- With low feed prices and healthy demand for broilers and eggs, the Mississippi poultry industry is poised for another productive year.
