I do have a turner in there to do it for me, but I guess what my concern is that the temps will be different (probably higher) right now then they will be once the fan comes and is installed so I will have to re-adjust. So im not sure if that would be good for the eggs to go from still air, to having to sit back out for 20 mins while hubby installs the fan and then have to check to make sure the temp is correct once its running. If it's not, then the eggs will either be sitting in it as it's re-adjusting, or be sitting back out until it's the right temp..Yes, go ahead and put them in, turn them until the fan comes. Yes, fat end up, if you got them yesterday, you could put them in this morning. Go ahead and put those that look like they have detached air sacs, they can fake you out and be just fine.Don't toss any eggs until day 10.
