Good morning all!
Momma Muscovy disappeared (predator?), and I now have 12 eggs in the incubator. All are viable. I'm not sure exactly when she started setting, but based on weight and air cell size, best guess is they are approximately 12-14 days along. The lowest weight is 71g and the highest is 84g. The air cells are all fairly consistent in size. They are in a Little Giant incubator with a fan. Temp is holding at 99-100* and the humidity is averaging 33-36%. I haven't added water but will start misting them today.
I've been reading the Muscovy egg incubating threads so I think I'm doing thing right so far, but, I'm absolutely hopeless at math. Could someone tell me how to calculate the weight loss percentage in grams for when I weigh them again?
Thanks!

What weight loss percentage are you looking for?

I think I'm looking for how much they lose each week....If I read the hatching thread correctly. It says they should lose 2.8%. For example, if an egg that weighed 71g today and 67g this time next week, what's the percentage lost? I don't know how to figure that.

What elevation are you at? I've read that one should take that into consideration when incubating.

I think that percentage loss is about 5.6%, but let me double check and get you a formula that you can use.

A 2.8% loss from 71 grams would be a loss of 1.988 grams to equal 69.012 grams.

Edited to make sense, lol.

Okay... Here's the math

71 gram egg now weighs 67 grams.
That's 71-67=4 grams lost.

4/71 = .056

.056 x 100 = 5.6%

If my instructions are confusing, just let me know and I'll re-write them.

If your goal goal is to lose 2.8% the math would be:

67 gram egg x .028 = a loss of 1.876 grams
67 - 1.876 = 65.124 grams

Hey we have four ducks. Three of them are 6mon old And one is about 4 mon old. We have the 4 month old in a pin by herself. We are trying to get her In together with the other three. We have two males. I think one of the male duck have mated with the other female. Should we let the male that hasn't mated yet mate with the 4 month old before we let her out or will they both have to mate her
