Silkies are good mothers, for about 6 weeks. They aren't even fully feathered yet.I never had problems with broodies rejecting their chicks. And I have been reading silkies are good mothers too. But …
I hadn’t thought about very cold weather and didn’t look for your location until now.
Canada! What is the temp in March where you live shortly after sunrise? Im afraid it’s too early in the year for young chicks to walk around outside even with a good mother hen.
This makes a brooder with chicks inside the house probably a much safer option.
Our brooder(s) are in the house. When they (silkies) get two months old or so in the winter, then we can put them in the parrot aviary that has a hutch inside with a cozy coop heater in the back. In the summer, they go out there when a few weeks old.
The majority of the aviary is covered with white greenhouse tarping, but there's an open area where the free rangers will come gawk at them, but we cannot put them in the coop. Silkies are sweet but relentlessly cruel to chicks/chickens smaller than they are. In trying to integrate, nothing before 5 months old has ever worked. If our coop was larger, we could build a pen in there, but free ranging together is about the best we get until they're old enough to join them in the coop.
