I have a pond with fish, but no ducks.

Well, what are you waiting for?

WHY do we need less humidity to get the best weight loss for colored hatching eggs during incubation? Marans being the best example! Bj's purty eggs are in the image below

First you have to understand egg shell composition! Eggs with white shells are made almost entirely from calcium carbonate (CaCO[SUB]3[/SUB]), and 5%est. of egg shell is made up from other minerals such as calcium phosphate, magnesium carbonate, and various proteins. As an egg is produced, it goes through the hens oviduct, which consists of five parts, Infundibulum, Ampulla, Isthmus, Uterus and that there Vagina. Taneggs or brown eggs can vary in color depth, the color seen on these eggs is actually a pigment/coating applied during the last few hours in the hen’s uterus and isthmus, see image below. A tiny amount of this brown pigment over a white egg will produce a light tan egg, a lot of this pigment will produce the dark brown Marans eggs. Since this color is not actually part of the shell and "painted" on the surface you will see that it can be rubbed off and scratched when its still wet, note the scratched eggs in the image above. Now we should all understand this part...... A Marans hen sends out thick coatings of pigment/protoporphyrins, which are by-products of blood synthesis, and deposited during the long hours passing in the uterius/egg duct and then finally in the BLUME stage, and those proto things, well they fill in thousands of spores in which create a dark beautiful egg, and in turn make the shell thicker. STOP WAIT WHUT???? Of course there are other factors involved, thickness of shell from calcium intake, size of eggs, and so forth, but with understanding the entire egg shell composition we can easily understand WHY there is a need to lower incubation humidity compared to commercial hatcheries that hatch white eggs, and why some breed eggs need a much much lower incubation humidity to reach the correct weight loss. .

@gotro17

I thought it was slower? Shouldn't think you would need to mess with humidity after lockdown though.

there read that i was wrong dont quote me

Thank you so much Liz!!!

Hatch day for HennyPenny II and Reynbow's chicks is in 2 days! e
(That is, if they are alive. Never checked them. I hope so, because HennyPenny has been broody for over two months now)

What is crazy?

the chicks

 

[jwlpoultry]

I am so nervous. I leave on Sunday and won't be home for 5 days and my brother and sisters will be taking care of all my animals but is so stressful not knowing that I know that they are done exactly right.
