How many chicks can a hen usually hatch?

Nowadays, hens are rarely used to hatch eggs. You can hatch eggs if you want, but generally hens should not hatch too many eggs. Just give them 6-8 fertilized eggs. Too much incubation is not good.

You can buy some on the day when the chickens hatch and put them in. If the old hen doesn't know them, you can take them all away, but not too much. At most, there are more than 20 chickens. It's too big for an old hen to take care of.

If you can't buy it that day, you can also buy it one day in advance and leave it outside. The eggs hatched by the old hen are about to hatch, then put them in.
