This cooling feature is an option which can be enabled to improve your hatch rates. Cooling is not recommended for parrots and birds of prey because the results of cooling for these species haven't yet been established. duck and goose) are cooled for 3 hours each day from day 7 through to 2 days before they are due to hatch (the same point that automatic turning would normally be turned off). The cooling feature can also be found on the older Brinsea models of the Advance and EX versions of the Mini, Octagon 20, Octagon 40, OvaEasy 190 and OvaEasy 380 models.īrinsea have assessed the available research and recommend that smaller poultry, waterfowl and game bird eggs are cooled for 2 hours each day and larger eggs (e.g. This function applies to the Advance and EX versions of the Mini II, Maxi II, Ovation 28, Ovation 56, OvaEasy 100, 190, 380 & 580 incubators. The most common way to monitor humidity levels in the incubator is by using a digital hygrometer. The default setting is that cooling is set to off. There are 4 main ways you can keep track of humidity levels in the incubator: a digital hydrometer, weighing the hatching eggs, using wet bulb readings, or monitoring egg air cell sizes. The cooling function is optional and the user can select cooling periods of 60, 120, 180, 240, 300 and 360 minutes with fixed 24 hour intervals. After the cooling period is complete the incubator reverts to normal temperature and the alarm is automatically reset. For this reason Brinsea have incorporated a cooling option in all of their Advance models of egg incubators since 2012.īased on the results of the research paper above the user of an Ovation 28 Advance could expect one additional egg to hatch on average.īrinsea's cooling feature turns the incubator's heater and low temperature alarm off for a selectable period but keeps the fan running. From Brinsea's 40 year experience, the best hatch rates are always achieved when the incubator can best mimic the natural nest conditions.

This morning when I put in a full glass I heard water running.Bird breeders have known for many decades that eggs can be cooled for limited periods of time during incubation without causing problems but recent research has shown that hatch rates can actually increase significantly as a result of cooling. I had the bator on a furniture pad on my antique cherry hutch, so until I added a full glass of water this morning, the pad was apparently absorbing what leaked out. No where in the instruction booklet did it say that, no one else told me that.I was told by one person to put water in the bottom tray outside of the rings when I initially had probs getting the humidity up, so when I have been adding water- instead of moving the egg tray out of the bator, I have just been pouring it in beside the egg tray. I did not know there is HOLES in the bottom tray. I still could not get humidity above 36% and was adding a half a glass of water when I turned/tipped eggs twice a day.was really confused. Best place for the incubator is a closed room, no drafts. Go and buy a cheap digital medical thermometer from Walmart and insert the point at a level with the top of the eggs in your incubator. When I correct humidity, I add warm water. First, the thermometers furnished with the little incubators are just trash, accurate to only +/- two degrees in most cases. To test humidity- the thermometer is also a hygrometer, so always know what it is. I don t actually turn them.have them in a plastic egg tray that has open bottoms and use a block under one side that gets moved to other side twice a day. If I need to add water I do it through one of the plugs or when I am "turning" eggs. I only open the bator twice a day when "turning" eggs. The bator is in my bedroom on a hutch, away from the window and doors (no heat running through vent- have an electric heater in there which keeps the temp stable) as that is the room with the most stable temperature and the door is always shut as I don't allow animals in my bedroom uninvited, plus that is the only room I keep heated at all times since my sleep schedule and hubbies are different and vary from day to day. They have been in the bator since Sunday. Purchased a digital thermometer/hygrometer which is sitting in the incubator next to the eggs. OK, I am not using the thermometer that came with it.
