Innformation for incubating(chickens only)

This is just simple things, we have only started incubating and the eggs are on day 9 today. Later on we will put new info on with better tips with incubating once we have had more experience, as well as how to hatch other types of poutly/fowl.
First, you need an incubator, second you will have to have some eggs.
If the incubator is new, 1 to 2 days of testing should be done to make sure the 'bator will keep a stable temp and humidity, and if it is your first time with an incubator it will help you learn how to make the adjustments to keep it as stable as possible.
Try to use the most freshest eggs you have, any over 2 weeks are not viable. Also do NOT put them in the fridge, they may be fine, but you will probably make the eggs less viable. Most say it's best to keep the eggs stored at around 60-65F. When you are ready to incubate, get the incubator all set up and ready with the temp/humidity. You will want a thermometer to know the temp, more than one meter can be good, but they also may be 5 degrees different, so test them out when you test the incubator. You will also want a hygrometer to test humidity, test this as well.
For most of the hatch, the temp will be around 99-100F/38C and the humidity..that can differ, some have theirs at 30% others 50%. We have ours at 50%, although we started out at 35-40%. You add water into a tray in the incubator to make it humid. On about the last 3 days, the temp will be the same, but you want to get the humidity up to around 70%. The last few days is often called "Lockdown". You do NOT want to open the incubator at all to check or candle the eggs.
And on the subject of candling, you will not really see anything until around day 3. Try not to candle too often. If you see eggs with nothing going on in them, depending on the days your on. If you first candle on day 10, then you can just toss out any eggs that show no development, if you're on day 3-5 you might want to wait a few more days just in case.

With storing older eggs, you can use older than 2 weeks, although the probability of development goes down. Also, it is good to put the eggs BIG END up in an egg carton, this way they are held well and you can tilt the carton from side to side everyday. Tilting it helps to keep the yolk from sticking to one side of the shell.
