Kit Fostering

[Pheasant283]

Have 1 CA that had 10 kits on Thursday. Have one more CA due any time. Was thinking of fostering a couple of Kits from doe that had 10 kits to the other doe if she has 6 or less. How many days older can the kits be from ones that are just born for fostering?? I am not wanting to go more than a couple of days.
