Incubating duck eggs in a Janoel12, all is well so far. Three pekins, two white crested, two blue runner. We are on day 23 now. I NEED HELP!!!! I have so many questions!!!! @RubyNala97 @WVduckchick @ChickNanny13 @HappyDancin' THIS WILL BE LONG BUT I REALLY NEED HELP!!!!! READ IT IF YOU'RE HAVING TROUBLE SLEEPING!!! THANK YOU IN ADVANCE what this post addresses: 1. air cell size?? 2. ventilation 3. humidity 4. tempterature 5. humidity again because I'm incompetent 6. WTF IS A WET BULB AND DRY BULB?! 7. Hatching tray? 8. Incubator set up Any advice is more than appreciated!!! Here are my billions of questions! let me start by mentioning that my eggs are in a real incubator right now, but i want to switch them into this "hatching incubator" so that i can observe them through my little peep hole (no pun intended ) so all of the issues with this current incubator.... they are not currently effecting my eggs BUT COULD BE SOON AND THAT'S WHY I NEED YOU SMART PEOPLE TO HELP!!! I'm clueless here! 1. I am afraid that the air cells are not big enough, will they grow in the next couple days prior to hatching? The embryos are filling nearly all of the shell part that is not an air cell... I would say they look like this... (excuse the drawing and no they are not blood rings, its just the little bit of space i can see between the embryo and the air cell...) is this large enough for day 23? Is it too large? I am so scared!!! 2. How much ventilation does my incubator need, and how do I tell how long it takes for the air in the bator to fully replace itself? I read somewhere that the ideal time is 1 hour. This is a hole on top that i cover and uncover... I will include a picture of the entire thing. Besides the one hole on top w black tape, the other "holes" are actually covered from the outside with glass so I can watch the hatch. (^that straw thing is my way of adding water to the largest water tray in order to control the humidity without having to lift the top off) 3. I can't get my humidity above 54% no matter what I do. I have added water galore, not depth wise, I mean surface wise. I keep adding little water containers throughout the bator to increase the surface area for the humidity to increase but nothing is working! 4. I have a mini fan in my incubator.... With it the temp is 35ºC, without it the temp is 39ºC. So far I have not been able to get a solid 36/37 (which is the ideal hatching temp right?) 5. Can the humidity be as high as I want or is there such thing as "too high" during lockdown? What would be considered too low at lockdown? 6. WTF IS THE DIFFERENCE BETWEEN A WET BULB THERMOMETER AND A DRY BULB THERMOMETER?!?!?!?!?!?!?!?! I have read sooo many things and I just don't understand. Idk what kind mine is but here is a picture.... 7. Do I need a hatching tray? I assume that means an egg carton with the bottoms cut out so that the eggs don't get knocked over by each other... but will they be okay without the tray if they are on the rubber mat? What do you suggest? I am nervous to use a carton tray because I have read that the ducks could pip on the wrong side and end up suffocating. 8. The way the bator is set up is like this: Large styrofoam cooler. 25W incandescent bulb inserted through left side of the cooler. Beneath the light bulb are four small holes with straws in them, leading outwards from the bator. These are part of my ventilation and air circulation attempt. In front of the light bulb is a mini fan which I can turn on and off without opening the incubator. Next to the fan on the floor of the bator is a little mini tray with water in it, which is refilled from my straw contraption on the side. A peep hold covered with a piece of glass is about one inch in diameter and is facing directly at the water tray, so that I know when it needs a refill and when it is about to overflow if I add too much. Above all of this is a diamond shaped hole that I can cover and uncover with the attached piece of duct tape. There is a baking drying rack covered in a stretched rubber shelf liner, vertically separating all of this from the hatching zone. You can see it sticking up in the full view picture. In the hatching zone, there are two view windows covered with glass, one above and one on the side. There are six straws towards the top of the cooler wall intended for ventilation. The only thing in this section (besides a horizontal cooling rack covered in rubber shelf liner, is the thermometer stuck to the side of the wall. I put it kind of low, so that it can be at the same height as the eggs. AM I INSANE?!?!?! should i just leave them in the current bator and hope for the best? I can't see inside of their current one at all. If you need to see more pics of my homemade incubator in order to better understand all my blabber, please let me know and I will post right away!!! I only have two days until lockdown, I really want to get this right! THANK YOU FOR READING ALL THE WAY DOWN HERE I REALLY HOPE YOU CAN HELP OR THAT THE ADVICE PPL COMMENT ON HERE CAN HELP YOU IF YOU ARE AS ANXIOUS AND CLUELESS AS I AM!!!!!
