Hi all, I am starting my 3 setting of 41 on June 15, with a goal of getting 34/41 fertile eggs, and hatching 100% of the fertile. This will give me 100 1st generation layers of my project breed this year...part of my project goal. My first setting resulted in 50% hatch rate, I did things according to the instructions that came with the Styrofoam incubator (Hovabator 1588 with automatic turner). Then I read Sally Sunshine's Hatching Eggs 101...that is a must read if you have never hatched...and even if you have, its worth a rescan.
My 2nd setting has so far resulted in 22/34 fertile hatches as of mid Day 21, so my hopes are up for a 100% hatch. For this 2nd hatch I paid a lot of attention to Pete55's thread A Guide to Humidity, Weighing and Lockdown. Again, full of lots of great information and well worth the read. Between the 1st and 2nd sets, I bought two things I think are worth the expense, a Brinsea High Intensity Ova Scope, and a $10.00 jeweler's scale that measure weight between 0.01g and 200.00g. Your goal should be 13% weight loss between setting date and Day 21. The formula is:
Ideal Weight on Day X = Start Weight - (Start Weight * 0.13 / 21 * Current Day Number)
So, if Start Weight was 58.44g:
Ideal Weight on Day 10 = 58.44g - (58.44g x 0.13 / 21 * 10)
Ideal Weight on Day 10 = 58.44g - (7.5972g / 21 * 10)
Ideal Weight on Day 10 = 58.44g - (0.361771g * 10)
Ideal Weight on Day 10 = 58.44g - 3.61771g
Ideal Weight on Day 10 = 54.82g
If you find your actual weights are above the ideal weight, then your humidity is too high (typical)...take the cover off for a while and stop adding water.
Another good tip is before you actually set any eggs, run your bator for a couple of days with no water and see what the humidity is in it. Your ambient air is going to have some humidity. I ran my last set as dry and couldn't get below 25% humidity...but 25% kept me almost entire on target. The other thing to remember is to take the average of all your eggs weight loss and work with that till at least day 18. In an ideal world, you'd have 2 bators on Day 18, one you put the eggs that are on target, and the other you put the ones off target.
Well, that's a lot of info in the first post, but I was hoping this stuff could be all brought together so everyone who participates get's the benefits I have had here.
Tell us what you are putting in your bator, what kind of bator (or broody) you are using, your expected lockdown date, and your reason for hatching (pets, food, show, project, etc...) and of course give us lots of pictures and videos. Videos of eggs chirping are the most awesome for me...
