Incubator Candling & Humidity

[skcrosthwait]

I am looking at getting a Sportsman Incubator and have read where people cycle more eggs in the racks every week or so and move the hatching eggs to the bottom hatcher. I have also read that on day 18 you need to increase the humiodity level several %. Wouldn't this effect the other hatches? If you are using this technique would it be best to keep the humidity level steady the entire time?

I think people that do that in a sportsmen keep the humidity consistent. Something like 60% I think.

I have a sportsmen clone I use for 1-18 but use a separate incubator for the last 3 days.

That's what I thought. The term the guy used was cascading the hatches. The other option would be to have a separate hatcher for them but I cant afford to buy one just yet.

The term they use on here is staggered hatch.

You can always build a hatcher.
Here are plenty of home built incubator/hatchers
