incubators are homemade.
My opinion is that must be increased the humidity or decrease air speed.
I like proggram at thread : https://www.backyardchickens.com/t/729494/emu-hatch-a-long-2012/90

Then I have a 49 Day incubation chart you can open and edit as you please with that program:
https://docs.google.com/file/d/0B2h04KL5_5FHZlp0MFpUREFiNjA/edit
To use it, simply weigh the egg for the first time and type the weight into the first empty space in the blue (Labeled True) and all the projected weights will be automatically filled in, including the weekly weight loss and daily weight loss. There's a chart below (Scroll down) which will display the weight loss and dates.
The actual dates at the top of the sheet can be edited too, just click on January 01, then there's an edit bar up at the top with the date in 1/01/2012 format which you can change to the egg set date, the rest of the dates will automatically update, you only need to edit that one.
To create more egg entries, just copy all the whole thing and paste it below the first entry. If you have eggs set on different dates select the row with the dates as well and then you can have two separate weigh dates, just edit in the new date and you'll be good to go. (Click for larger pictures)
To create a new chart, you just copy the existing chart and paste it below, then right click on the new chart and click 'Edit' at the bottom of the menu that pops up.
Right click on the chart again and select 'Data Ranges' and you'll see a text box with a button to the right of it that says 'Select data range' when you put the cursor over it, click that button, then scroll up to the egg sheets then click and drag over the sheet you just pasted starting from 'Egg ID' to the end of the blue row. And that's it, the new chart will automatically update with the date and egg weights for that egg.
If anyone has any trouble I'd be more than happy to set up a chart for you and upload it, just need to know how many eggs you have and what temperature you'll be incubating at, then all you'd have to do is type in the egg weights into the blue line as the weeks go by.
Making a chart for a longer incubation is a bit more complicated but doable, it mostly revolves around knowing/guessing the general date they'll hatch, I'm incubating mine at 96.5 so I have my chart set for a 53 day incubation (Just a guess mind you, they could hatch 2-3 days on either side of that date for all I know).
