Getting ready to put eggs in tomorrow am. Should I try to lower the humidity first?
Put in the 2 red plugs and temp & humidity went up right away, so I removed them again...
You should be aiming for 45% humidity for day 1-18 if you are incubating chicken eggs. Humidity should be measured as an average over the entire incubation period. Short variations in humidity over the incubation should not be a problem. Eggs need to lose enough moisture in order for the air cell to grow large enough.
65% humidity should be aimed at for lockdown to ensure the chicks don't dry out in the egg and become shrink wrapped. I would remove some water from your incubator to try and lower it. Good luck with your eggs
Thank you for the advice....After I removed the plugs again it came down to 65%...I emptyed most all the water to see how it stabilizes now...Planning on putting eggs in tomorrow am, so I hope I can it to the proper numbers..
Humidity is determined by the surface area of the water not the amount of water, remove water completely from one or more of the reservoirs to lower the humidity...
I opened it and emptyed all the water out and am waiting now to see what happens.
Foam incubators will take a day or so to go all the way down to now water humidity when the water is removed. Moisture is held in the foam.
I use little glad cups for humidity. They raise humidity 5 to 10% each. I have been incubating at 30 to 35% humidity, which is considered dry hatching since it is below traditional humidity for incubating from day 1 to 18. On day 18 I shoot for 65 to 70% humidity.
See, there is a cut out on the lid that allows the moisture out.
Awesome advice, thanks.. I'm watching closely & humidity seems to be dropping about 8-10% an hour..hopefully I'll have it stable by morning to put the eggs in..
entering 3rd day temp & humidy have stayed pretty much in these areas...mostly fluctuating when I add water...
If it stays around 45% without adding water have you considered trying the 'dry hatch" or "dry incubation" method? I'm doing that for this hatch I am in at the moment. Mine reads 40-45% w/o water in the wells, so I have not been adding water. Tomorrow we go into lockdown and I will up it to where it needs to be, but presently the growth has been on target and the air cells have been looking pretty spot on to me.
