I have a Silkie hen who's been broody for just over a week or so. I haven't let her sit on any eggs (there are other hens laying and she'll just go and sit on them until I take them away daily), but now am thinking about giving her some to hatch out (or try). Has she been broody for too long already for that to work? Is it too early in the season (I mean too cold? I live in NY. We've had great weather for a few days, but it is still February)? Any broody hen tips?
