Wow first ...
second, Have you researched on here in the incubating section? lots of great info
Let me see if I can break this down into short easy answers
The hens have started laying eggs. And since I don't own an incubator I was thinking of letting the hens hatch the eggs. So, I need some information on how to hatch eggs by the natural method.
How many eggs should I give per hen? Your hens have to go broody first before I would give them any. Meaning, They stay in their nests all day and night only to get off to eat and drink some and to poo. You cannot force them to be broody either. They have to be in that frame of mind all on their own. When you get a broody hen, the amount of eggs you put under her depends on her size..Is she a large fowl or a bantam?
Will I need to provide heat? No heat needed-the momma can keep the eggs and chicks warm without a problem-unless your allowing it to take place in the dead of Winter-then i would supply a heat lamp-just in case.
Will the rooster be a problem after the chicks have hatched? sometimes, as will the other hens. I use a broody cage-its a large cage with bedding, water, and chick crumbles, only mom can get in with the eggs and they will be seperately kept in same room as other chickens-to prevent chicks getting killed or lost within the others.
Will I have to separate him? Maybe and or the other hens as stated above
Will it be better to remove the chicks after they've hatched or to leave them with the mother? NO-not unless you see the mother attacking or hurting her babies. I wouldn't want to raise the babies my hen spent so much time working on-they are hers. I have never had to remove chicks but it does happen where the mom will attac and kill them the minute they hatch...Just keep and eye on them and see how it goes-if she hurts them -remove them and raise them yourself in a brooder with a heat lamp chick feed and water....
