I have been following the advice here and this season set the humidity of my RCom 20 at 45 until day 18 and then crank it up to 65 for the last 3 days.
Previous years I had set the humidity for 55 all through the 21 days.

Both ways seem to give the same result however last time when I was incubating eggs sent to me by post, I cranked it up to 65 for the last three days I had one chick that pipped but then died and 5 chicks that died in the shell. As this was from posted eggs I blamed that as I have not had a non-hatching result previously.

Does anyone have any thoughts on what the humidity should be set at?
Would it be better to gradually increase the humidity over the first 18 days so that it arrived at 65 on day 18?

It was happening to me when i started incubating eggs in the bator.
I used to set the eggs up side down, should be down side up. Might be the case???

In my Rcom I set it at 45 to 50 then up it to 65 the last three days. It seems to work for me. But no idea what is going on with yours.

There is only 1 position to set the eggs in an RCom 20 and that is to put the eggs on their sides.

There is nothing wrong with my RCom, it is functioning perfectly and is just doing what I have set it to do.
What I would like to know is if anyone does anything different regarding setting the humidity?

For chickens I would do the same as NellyG.

I really doubt that the increase in humidity would have had any effect at all on the viability of the eggs. With posted eggs dying at that stage I'd be looking at the nutrition of the parents as the most likely problem, and inbreeding would be next on my list.

With posted eggs (or eggs that have traveled) you must put them in an egg carton, pointy end down and let settle for at least 24 hours. This may be the case with what is happening.

I don't think that resting the eggs does much tbh.... I think it's more important to get them in the incubator asap, instead of letting them sit around getting older. That's my view on it anyway.

i agree with cocoa on this. I have done both and really haven't seen any differeence in viability except that they are a day older before you start to incubate, which with posted eggs is not a good thing as they are generally getting a bit old by the time you get them.

Same here. I like to give them a couple of hours to settle but think that 24 is overkill. Generally sit them on top of the bator as it is warming up and set them when it is stable.

Can anyone tell me exactly why humidity is boosted from 45 to 65 at 18 days?

It's just to stop the membranes drying out too much as the chick hatches. And it also just mimics what happens under a hen - as the egg shells crack and moisture starts to evaporate and wet chicks emerge, the environment under the hen becomes more humid. Nature knows what it is doing so if we replicate that then we increase our chances of success :)
