I have three broody hens. Two are silkies and one is a silkie, bantam-of-some-sort cross. If one gets up to get a drink and some food, another runs over and sits on the eggs. At night, whoever is sitting on the eggs goes into the coop and goes to bed. Another broody will take over and in the morning, they will switch again. Is this normal? Chickens have a flock mentality, I know, but this seems a bit excessive. Last year, I had two sisters brooding together, but on separate clutches. Has anyone else experienced this? I love that they take turns, even if it may just be for a selfish, broody reason. lol.
