I would not panic too much, lots of bitches don't seem to need the full 24/7 contact with the pups. As long as she is happy to feed them regularly and clean them up I think everything is OK. I find that trying to force a bitch to stick in the whelping box can stress them if that is not their inclination. I think you may find the room temp is a little high for her - I keep the pups warm with a heat lamp, and the ambient temp at about 70 to 72 in the rest of the room for the first 2 weeks. Mildred, who is currently feeding alitter of 6, is eating 3 times per day, and is on about 4 times her normal food quantity. I am ahppy to feed nursing bitches as much as they want (within reason - normally greedy bitches have to be watched for taking advantage of the situation). Make sure the protein and calcium content is kept up - I give goats milk as well as adding chicken, fish, eggs etc to complete puppy feed. IF she seems generally restless or upset, then a calcium injection could help.
My American Cockers tend to react maternally pretty much the same as Cockers, and my girls like to stay in a puppy pen which is around the whelping box, , popping into the box to feed and clean, but mostly staying just outside in the pen, resting and watching, although the odd one has insisted on staying in close contact with the pups all the time, having to be hauled outside to go the the loo! However, my pugs are much less maternal, my last girl to have a litter lay on my bed close to the whelping box and watched, but did little else! Mildred is currently happy to go in and feed (accompanied by me) on a 4 hourly timetable now, and is cleaning them beautifully, but spends no other time with them. She is downstairs with the rest of the bunch, enjoying the extra grub on offer.
As long as she seems happy and settled, and the pups are obviously gaining weight beautifully, try and enjoy and don't stress too much - I can vaguely remember my first litter, way back in the dim and distant past, and it was exciting and terrifying!
