The Fertilization of a Chicken Egg

Basic Reproduction Explained

As in all animals, the fusion of the ovum and the sperm is how fertilization occurs. Then an embryo forms and develops into a new organism. The chicken is no exception; their eggs need to be fertilized in order to develop a chick.
A chicken will begin laying eggs between five and six months of age, until then she is called a pullet. However, climate, seasons, and other various factors do play a significant role in laying cycles.  Certain breed types are also included in the variances of egg laying, first-time or otherwise.  One thing is for sure, when a pullet reaches sexual maturity she will lay eggs whether or not there is a rooster present.
Roosters [males] have reproductive organs which produce sperms that are released during mating.  The sperms enter the oviduct of the hen [female] and continue a nearly week-long reproductive journey to meet the eggs. The sperm’s final destination is in the infundibulum. This is where they will wait about a week for the partially formed and unshelled eggs. If there is a yolk, the eggs are fertilized instantly. So, it’s safe to say you can expect fertile eggs seven to ten days after mating.
Note:  It is possible the hen may produce fertile eggs the following week as well.
When hens are in the presence of a rooster there is a way to separate the fertilized eggs from infertile by a technique called candling.  This method uses a bright light source behind the egg to show details through the shell. Fertilized eggs will show a darker yolk on one end, usually when they are one or two days old.  Within two to three days, if incubated, you may actually see indications of a growing embryo.

Raising Winter Chicks in Phoenix

When Can Chicks Be Moved Outside in Phoenix?

It’s a good guess you have your new chicks in a box in the garage or shed and are watching them quickly outgrow their safe haven of comfort and warmth.
At about 6 weeks old they are becoming a handful, looking a bit crowded in their quarters, and you’ve had enough of keeping up with the mess. I understand your dilemma and have good news for you. We live in Phoenix! With mild winter temperatures, even at 6 weeks, your chicks will be fine outside with the right housing accommodations. However, first, you’ll want to lower the temperature in their brooder over the next few days to get them used to cooler temperatures.

A suitable coop for 6-week-old chicks is something that will protect them from wind and rain. If your coop is drafty, a large tarp will do wonders. Buy the highest-grade tarp you can find, or use two.
If there’s a cold snap, say below 50 degrees, simply cover the coop with a heavy blanket. Moving blankets from Harbor Freight work great and they’re only $8. The chicks will huddle together at night and keep each other warm.
Give them lots of shavings or hay in the coop, and provide a low-sided brooder box filled with shavings in the corner for them to sleep in. If they don’t use it, that’s okay too.

Prepare for the Phoenix Heat Now

While watching your chicks grow in the confinements of their coop, this is a good time to think about summer’s arrival and prepare for their outdoor environment. Keeping chickens in Phoenix is tough, keeping them in small confinement quite honestly… can be a death sentence.
June and July will no doubt reach 110 to 115 degrees. This means, your coop could easily exceed 120 degrees, even if it’s in the shade. It’s imperative to provide a play area where they can dig holes in the dirt to stay cool.
A play area can simply be a fenced area off the coop. Look for or create a shady spot preferably near a water source so it’s easy for you to access. This is important because there will be days when you’ll want to use a mister, or maybe flood them a spot to help them cool off.

I wasn’t kidding!

How to Bathe a Chicken

Showing Your Bird?

You’ll need 3 buckets; any will do, but I like the 5-gallon size.  Use Ivory liquid soap in the first one for the bath. You can add 1/2 cup of 20 Mule Team Borax to the bath for a positive effect if your chicken is light or white.
Fill a second bucket with water, and use this to rinse the soap off the bird. If your bird is white it’s okay to add 1/2 teaspoon of bleach to each gallon of water. This will help brighten the white.
In the third bucket mix 2 cups vinegar with each gal. of water, this will make the feathers shine.  If you want that show shine appeal, add 1 tablespoon glycerin.
Gently pat the chicken with a towel, or confine to a clean cage to dry. Using a blow dryer is okay too, just make sure it’s not too hot, and diffuse the air stream with your hand at all times.  The blow dryer can frizz or break feathers, keep it on low and take your time.
