Our silkie decided to go broody this week and is now sitting on a clutch of 12 eggs. These are our first chickens (and had actually only been getting eggs from them for about a month LoL Brats!!) and while we did get these guys as chicks they were about 3 weeks old and we lived in an old house that had radiators and just kept them in a box against the rads with a blanket over top and they move closer or away as it they needed to stay warm, it worked really well for us. I'm just really paranoid about a heat lamp in the house and we don't have any barns or outbuildings. We're in Ontario and it's getting pretty cold at night here, like low 20s will we be able to leave the chicks with their mom or should we be prepared to bring them into a brooder box?
