I'm not interested in an incubator but was considering buying a hen, since I have a rooster, and raising some chicks in hopes to get some laying hens. We live in Mexico where I'm not going to be buying imported chicks from the US but "mutts" from a friend of a friend. Before I do this, I was hoping to get some points straight. 1)If a hen starts laying, with intent to brood, she'll automatically stop laying eggs after say 6 eggs and sit on those for 21 days? 2)After 21 days the eggs will hatch if they're all good? 3)Unless the hen pecks, with intent to kill, the chicks, they can live with her? Our climate is mild year round.
