Attempted to rescue puppies

Question
My male dog has been hanging around with a female who obviously just had puppies, I went walking to find my dog and when I did I found the mom and puppies 7 or 8 of them.  They are under wooden deck at an abandon home.  I got the puppies and them the mom got away from me. I know I should have left them but it's going to get down in the 20's tonight, I brought the puppies home hoping she would follow because she has been to my house with my dog, anyway I took them back in a blanket, do you think she will continue to nurse them?  I will be checking on them daily.

Answer
Well it won't hurt to put them out first thing in the morning,and it also depends on the age of the puppies,if they are very young,they could starve without there mother,but if they are over 5 weeks-but either way it would be a good idea to buy puppy milk,you can usualy get it in powder form in most petstores,then that way you don't have to worry about it

But it depends on how old they are how often you feed,the best idea would be for a vet to look at them and help figure out when to feed them and how much
