Nice commons! You do have seperate enclosures right?
As for handling, well I dont handle my big female as much as I used to. Probably about three times a week now, and the handling part is mostly just taking her out and putting her back in her enclosure because I normally put her down and let her get some excersise. I NEVER handle when she is in shed or for usually about three days after a meal.
I have NEVER fed my girl anything but F/T and I have NEVER put her in a seperate enclosure for feeding and I have never had a problem in almost 14 years with aggression. I always figured it was more stressfull to handle right after a feeding anyways. Wouldnt want to cause a regurge.
For the most part BCI's tend to have great temperments but I have had quite a few "nicks" from Suri's, Guyana's and even Mexican BCI's.
Enjoy your pets!!
