New question about humidity

[MissPrissy]

Shoot!

Thanks twigg! I somehow missed the duck egg! I get distracted by my son often times!

Raise the humidity to 65% for your duck eggs. I just hatched 2 batches of goose eggs and waterfowl humidity is 65%.

My bad! I am so sorry!

no worries, I just appreciate you all helping me out. The chart I have showing wet bulb method has the humidity the same for duck, guineas and chickens. Even during the last 3 days, it rises to the same higher levels for all 3 bird varieties too....
I have been planning on incubating the duck eggs for the first 7 days alone then adding chicken eggs for the last 21 days, in hopes that all will be about ready by the official 28th duck egg day and 21st chicken egg day. I know I've seen posts on here by people hatching out both at the same time... how'd they do it?

I would assume that would work so they'd hatch right around the same time. Are duck temps and chicken temps right around the same then?​

well, as far as I've read so far....humidity levels too, but it seems like everything I read tell me something different than the last thing I read. The link shown re Dry incubation in MissPrissy's post says he doesn't hardly use any water at all until the last few days. I'm so confused! Its still 62% and the room its in is 45%. The temp is still trying to regulate-its 98.8....

Temperature

During the warm-up period, the temperature should be adjusted to hold a constant 101°F for still air, 99°- 100°F for forced air. To obtain reliable readings, the bulb of the thermometer should be at the same height as the tops of the eggs and away from the source of heat. Using two thermometers is a good idea to ensure you are getting an accurate reading.

Incubator temperature should be maintained between 99° and 100°F. The acceptable range is 97° to 102°F. Mortality is seen if the temperature drops below 96°F or rises above 103°F for a number of hours. If the temperature stays at either extreme for several days, the eggs may not hatch. Overheating is more critical than underheating. Running the incubator at 105°F for 15 minutes will seriously affect the embryos, while running it at 95° for 3 or 4 hours will only slow the chick's metabolic rate.

An incubator should be operated in a location free from drafts and direct sunlight. An incubator should also be operated for several hours with water placed in a pan to stabilize its internal atmosphere before fertile eggs are set. Do not adjust the heat upward during the first 48 hours after eggs are set. This practice cooks many eggs. The eggs will take time to warm to incubator temperature and many times in small incubators the incubator temperature will drop below 98°F for the first 6-8 hours or until the egg warms to 99°-100°F.

Humidity

The relative humidity of the air within an incubator should be about 60 percent. During the last 3 days (the hatching period) the relative humidity should be nearer 65-70 percent. (Too much moisture in the incubator prevents normal evaporation and results in a decreased hatch, but excessive moisture is seldom a problem in small incubators.) Too little moisture results in excessive evaporation, causing chicks to stick to the shell, remain in the pipped shells, and sometimes hatch crippled.

Some people do hatch them together with success. Some hatch them together without success.​

oh thank you MissPrissy, I'll read thru that whole link. Its helpful to remember I just set them 6 hrs ago...I tend to be a perfectionist too which may or may not be a good thing here. I tell you though, I feel like a nervous nelly here with them. Hopefully all will be ok.
Will keep on adding updates here....or new ??? as I think of them.
Thanks again.

You should have a second therm as the accurite Temp/hydometer arent always accurate, just cause there new doesnt mean there right.

Just wanted to let you know that.

Question for you, do you remember what number the dip switch was set on when you recieved the bator??

thanks
Charlie

 

[chickenlisa]

nope, sorry. the temp has gone up to 99.1 now and the humidity is around 62%. I just put in a 2nd therm/hydrometer to compare the two.
Thanks
Lisa

 

[MissPrissy]

The hova may equal out just above 100 but that is okay. I have one that levels out at 100.7. I have good hatches in it.

Update on day 3...the 2 accurites are both inside the incubator....#1 w/ the sensor inside the water wiggler says 99.1 for the inside temp, 97.2 for the outside temp and 59-60% humidity... #2 w/ the sensor mounted on the wall inside the bator says 98.2 inside temp, 98.8 outside temp and 63% humidity. That sensor is higher than the one inthe water wiggler. Should I change anything? I still am confused about the temps...
Please help, anyone?
