To know for sure what you are eating you need to weigh your carbs dry and protein cooked, I've never worked shifts so eating must be hard.
That aside and assuming average portions for an out and out bulk though it doesn't look like a huge amount of food - my pre contest diet is 2500 - 3000 calories, bulking I carb cycle now but try for 9000 cals twice a week. I can't eat that amount consistantly as I just loose all appetite, but I don't think you are eating enough..
