I have a broody silkie she has been that way for three weeks now and I did try to break her but with no luck so I ended up getting her some fertile eggs yesterday.She will hatch out the end of this month.She is in the coop with all the other silkies in a box,after they are hatched out I will move all them into a dog crate in the same coop so I don1t have to deal with the introducing thing.My question is when I let the mama out the chicks will follow her outsdie and there is snow on the ground and it is very cold,how much cold can the chicks handle?I know in the fall when I have had babies they would get under the mama and when she thought they were warm enough she would go about her scratching and eating.I will have a heat lamp over the crate to keep them warm.Maybe just let her out for awhile and keep the babies in the cage.I ahve never had babies in the winter time and am not sure how to handle this.
