    I have 5 silkies. 1 rooster and 4 hens. They just recently started laying eggs (haven't been able to tell which ones) but the first two eggs laid were fertile because when I cracked them open I saw the bullseye on both (sorry chicks[​IMG]) so I decided to incubate the rest to see if any would hatch. They sat at 75-77 room temp (oops) and about 20-30% humidity before I put them in the incubator (BIG oops...)

    I live in Wisconsin and its bone dry here in the winter. It's day 5 incubation my humidity is 65% and temp is about 101-102 with an accurate thermometer inside the bator (although the incubator thermometer on outside says 92 degrees which is strange....) so here's the thing, there is NO embryo development whatsoever, NOTHING! [​IMG] I'm very sad and not sure what I did wrong.

    As you could probably tell, I'm extremely new to this and I've read tons of blogs, watched videos, articles etc but not sure what went wrong. I have a feeling it has to do with the temp/humidity I kept the eggs at before incubation but where the heck do I put them in this retched dehydrated chicken jerky like environment??? There isn't anywhere in my house that goes above 30% humidity. [​IMG]
    Thanks for your help!

    So many things here but let me start. Many of us store eggs for incubation like that and have pretty good hatch rates. How long did you store them like that? If it was less than a week you should have developing chicks.

    It’s not at all strange with that thermometer. They are tremendously unreliable. You say you trust that thermometer. I hope you have a good reason to actually trust it. I don’t trust any until I can check them out, usually using a liquid-filled medical thermometer I do trust to check them.

    Do you have a still air or forced air thermometer. That’s a little high for a forced air, those should be closer to 99.5 Fahrenheit. Inside a still air, hot air rises. It’s extremely important where you take the temperature. It yours is still air and you are taking the temperature at the top of the eggs, that’s pretty good. If you are taking it somewhere else, that’s not good.

    Some people can see inside eggs really well and may be able to see development after three days of incubation. The color of the egg shells, the equipment and technique you are using, and your experience all factor in. I don’t bother trying to candle my eggs until Day 7. Even then I can’t see anything in a lot of the darker green ones. I certainly would not do anything dramatic until a lot later. Normally I toss the clear ones when I candle at day 18, going into lockdown, not before.

    How are you counting the days? A whole lot of people get this wrong. An egg does not have a day’s worth of development when you put it into the incubator. It takes 24 hours of incubation before you have a day’s worth of development. Say “1” the day after you start. A good way to check is that you should say “21” the same day of the week you set the eggs. If you started them on a Tuesday, Day 21 will be on a Tuesday.

    You are setting pullet eggs. I do too, you can get them to hatch. But pullets are famous for laying strange eggs when they first start to lay. You might get soft or no-shelled eggs, extremely hard shells, double yolked eggs, no yolks, no whites, or just plain weird eggs. It sometimes takes them a while to get the kinks out of their internal egg making factory. These things plus a lot more need to be right for an egg to develop and hatch. A lot of them get it right from the start, but I normally don’t get really great hatch rates with pullet eggs. Sometimes things that you cannot see just aren’t right. The longer you can wait to set them, the better your chances.

    Another problem with pullet eggs is that they are small. There are just not enough nutrients or room in there for the chicks to develop into big strong chicks. Most of the ones I hatch from pullet eggs live, but the mortality rate for chicks from pullet eggs is higher than from eggs from older hens, even a month older really helps this.

    Right now I would not panic. Don’t do anything dramatic or drastic you might later regret. Wait a few days to candle again. Be patient and treat this as a learning experience. You still have a chance to get chicks out of this.

    Good luck!

    So I just cracked all 5 eggs open last night and not ONE of them was even fertile!!???!?? I am beyond confused. The first 2 eggs laid were laid on the same day and when I cracked them they very distinctly had the bullseye indicating fertility. So I assumed the rest of the eggs laid were fertile but they did not have a bullseye?? They even just looked like a normal egg, no development at all and smelled really rotten. So now what do I do? Incubate all eggs I get? Or can chickens lay a fertile egg and then not fertile or.....I am beyond confused.

    The rooster may have his favorites, and the fertile eggs may have been from them. Other people have said that fertility is worse in the winter, and once there is more light and fresh greens, fertility goes up.

    I wonder about how you said they smelled really rotten - that sounds like bacteria. Are your pens clean and dry and is there clean nesting boxes for them to lay in? Do you wash your hands every time you touch the eggs? Just things to think about as you go forward.

    Good luck on your next try!
