Probably a bit too late to do anything other than tuck them up for winter (and hope for the best).
I see you posted early in the summer and this is your second. You should really have been reading the forum regularly, referring to your mentor for assistance, or at least joined you local BKA in the meantime.
Do you mean they have only drawn to the outer frames (9 or ten frames depending on type) or including the outer frames?
If it does not include those two frames, I would replace them with dummy frames to reduce the space available to keep warm and add extra insulation - do it on a warm day while they are flying..
Probably should have fed sugar syrup much earlier, but it is now important to know how much stores are present and possibly feed candy later, as required, or even now.
I would make sure they were adequately insulated, depending on topography, prevailing winds etc, (you give little information regarding your colonies, actually), with appropriate ventilation.
You should have already treated for varroah, or at least checked regularly for mite drop to ascertain the loading in the colony. You may need to give a treatment around the end of the year (oxalic acid trickled on the seams of bees).
A very high mortality rate occurs in wild colonies in their first year - mostly due to starvation. Colonies need nurturing to get them established with adequate stores, and monitoring for health to enable them to have the best chance of survival over the winter months.
I wish you luck.
