If it is still air 102 is good.

Your best bet is to read Hatching 101 in the learning center. Read it all, then... read it again!
What kind of hatching success has she had with it? Did she give you the same thermometer(s) that she used with it? Is it a forced air, or still air? Did she use a turner in it? Is your house a bit colder than hers? How long have you been running it? Is it empty right now? My recommendation: Be absolutely sure that you have an accurate thermometer. If you're using the same thermometer that she was using, it's possible that the thermometer is off just a bit, or perhaps the thermostat control has been bumped a bit. Ask her about it. If she's familiar with it, she should be able to tell you if the thermometer is reading a bit low. Or, maybe, it is what it is, and her hatches have been a bit on the slow side, in which case you could bump it up just a bit. Either way, you should put a couple of water bottles in it and run it for a couple of days to get the temp where it needs to be, before putting eggs in it. goal is 99.5 for forced air, 101 - 102 for still air. Someone please correct me if I'm wrong on the still air. Read Hatching 101. Enjoy!
Could you try a more powerful light bulb, change the location (away from doors & windows) or wrap a towel for more insulation? ....Just brainstorming.It is low a homemade forced air with a wired on temperature control system that only goes up to 99 and is not very accurate. I put a small container full of water on the egg turner and put a temperature probe in it. After a while I tested the water temperature using a digital medical thermometer and it read exactly what the probe was reading. They said they get ok hatches with it but that was in a much warmer and more evenly temperature controlled basement during the summer.

Am I seeing a clear lid on the top of that bator? Perhaps plexiglass? If so, there will be a lot of heat loss from it. Covering that with a blanket will help immensely. I wish you the best. You've got quite the project ahead of you.
