Well just let the eggs stay in there. As gatorshark75 said 21 days is an average, they can also hatch earlier. The baby chicks inside the eggs can't count and will hatch when they are ready not necessarily day 21.;)
Creature life, I was also getting mallard eggs everyday so I thought why not try. I have started the incubator but I don't know the basic settings for mallard ducks as I used to hatch chickens.:/
Today is day one of incubation. I knew the basics temp at 37.5 and humidity at 55% but I have heard something about spraying water after day 15 and does it take 28 days or 25??? Reply fast.
Yes, there is bloody mucus coming from the mouth. One chicken which I cared since it was a chick just died in front of my eyes. Two of my older chicken ( black cochin, sebright) are also infected. A broody chicken which had 4 babies now has two left.
I have a broody chicken with babies and they are fine but the older chicken are the one getting infected!!!! The sneezing is like screaming and then their voice goes down. They are more like screaming than sneezing.
