Title: Humidity out of control!
Post by: Sharondp on April 30, 2010, 05:14:49 pm
I have a very basic incubator - it's automatic inasmuch as it turns the eggs and regulates the temperature, but it doesn't regulate humidity.

I have to put just the tiniest drop of water in and the humidty shoots up to 60%, With no water in, it is 30%.

Hubby thinks I may need to prop the incubator open a very tiny bit - what do you guys think - anyone any experience of this?

I'm about to candle the eggs tonight but I'm not holding out much hope - it's been up and down too much :(

Typically, my BO's have been broody all winter, as soon as I have a decent clutch of eggs, they're not interested! >:(

How about trying a spray mister?  Less water and finer droplets.

I did think about that, but thought you weren't supposed to get the eggs wet?

Can't you aim it into the incubator without wetting the eggs?  I haven't a clue really as I don't have one, but I know you mist the eggs near the end of incubation.  Could you take the eggs out for a couple of minutes while you spray then put them back in?

You need to increase humidity towards the end of incubation so I'll be OK with my tiny drop of water in the water thray then!

It would be a real faff to take them all out each day to spray.

I'm wondering if there is such a thing as an incubator that actually regulates the humidity - bet it's costly if there is!

60% is better than 30. try damp/wet kitchen towel. you can then take bits off until the right level. don't leave it open. that could wreck the hatch.

years ago I made my own incubator . It had 3 trays and took about 200 or so pheasant eggs per tray . The heat was supplied by a row of light bulbs fixed on a board with the light part placed in holes ,cut in the side of a pipe made out of empty tin cans . Above this I made a tray to take a small amount of water ( like the old paraffin greenhouse heaters) , I used a thin layer of sponge to help prevent water getting tipped everywhere.
 The heat was controlled by adding  or subtracting light bulbs from the rack , till I found out the number needed in watts .
The water, I just kept it moist but not wet . In this incy I hatched hundreds and  hundreds of chicken , guinea fowl , quail , ducks ,  geese, peacocks and thousands of pheasants . It cost me about £5 to make ....( it was 30 odd years ago ) out of a couple of sheets of ply and some 2"x 1" , a few light bulb holders , and a few other bits and bobs I had laying around .
 It worked perfectly , apart from I had to turn the eggs by hand . The thermometer was an old fish tank one and I never had anything to test the humidity.
 A tray of some kind with a bit of sponge/old towel, would provide enough moisture .

hope that sort of helps ....?  ::)

cheers

Thanks Russ - This one holds 16 eggs!!  :D

There is a water tray in there - maybe I'll try a bit of sponge or kitchen towel in it instead of just pouring it in - thanks guys - although we'll see if I need to continue after I've candled them later!

 ;D ;D ;D ;D

I have 11 (out of 16) viable eggs!

I have put a piece of kitchen paper in the water tray and will keep an eye on the humidity - thanks for all your advice - we'll see how the next 10 days go now!

wow, congratulations - that's not a bad batting average!  Almost 69% if they all hatch.  (yes, I know, don't count etc etc......................) ;D ;D
