48 egg incubator Air hole close or open ? 0 to 18 days

[aurimilky]

I have a 48 egg incubator with in build fan, does the air hole need to be open in the 0 to 18 days or can it be close for 0 to 18 days, then opened on day 18 until then hatch ?

What kind of incubator---brand/model would help? All incubators need some air exchange. Just need to know what you got?

I don't know the answer to your question but I have seen models like that and ppl say not to buy them they are poor quality,short out if I remember right one said theirs started to smoke. and another said it never stayed warm enough and hatch rate was poor.

I have the egg incubator in the polystyrene box to help with temp and humidity with air holes for the fan holes. Yes this hatch will probably be the last one using this egg incubator, I on my 4th hatch now, the other hatches didn't go very well. I got the eggs this time around for a broody hen, but her wont sit on the nest in the day time, so I had to use the egg incubator.

Well if you have been having good hatches with this-----I would just continue he same way, a lot of people that have bought these---need you around to ask questions---if you would be willing to help because most that get these have bad Hatches---if any even hatch.

Yes most of my hatches have been very bad. Some on my first hatch I only got two chicks out of this type of incubator out of 24 eggs.


My other 2nd and 3rd hatches. I had 48 eggs for the 2nd hatch and none of them hatched. Oh there was one chick that may have hatch, but I was on day 26 or 27, so I cracked the egg I had left, some of the eggs where died and the chick the was a live dead, but it probably wasn't go to hatch anyway. The 3rd I converted the 48 egg incubator in to a 56 egg incubator 56 eggs, so I had 56 eggs in the egg incubator. I even look around the forums and asked questions to help with the 3rd hatch. I was tolled to have to egg incubator at 35.5 to 39.5 and humidity to 35% to 45%, unfortunately this didn't help very much and I end up with 7 rotten eggs. So this time around I have it back to 50% to 60% humidity.

The best hatch I have had was from one of my hens this went broody, right now she has 6 chicks out of 12 eggs run around with her right now.

35.5 to 39.5 for sure will not work. When it got to 39.5 probably most of the embryo's die.

You stated above in post #5 that " I on my 4th hatch now, the other hatches did go very well" You must have Meant they DID NOT go very well???

With this incubator you GOT, Got, got to use another Temp and humidity meter---about everyone says the built in ones are Way off. Good Luck!

I forgot the C for the temp as its in Celsius.

Yes I mist out the n't on the "did" what should had been "didn't". Thanks for pointing that out.

Yes I've got a external temp and humidity meter for the my egg incubator. It works a lot better then the in built temp and humidity.

I knew that but 35.5c is to low and 39.5c will probably kill the embryo----to hot. Why is there so much difference in the temp?
