Can i mate my Masked lovebird with my fishers lovebird?

I purchased 2 birds, a masked lovebird and a fishers lovebird from pets mart 2 years ago. I felt sorry for the birds because someone purchased the other two and separated them. A friend has other types of birds, he recomend that I put a little house in the cage to see if they would mate. Well they did, after a month I saw egg shells in the bottom of the cage. Then about 2 weeks later I noticed Spike (female) taking food from Sam (male) I didn't think anything of it. When I told my friend, he said that's because she has little ones in there. I couldn't see anything so I took a picture, put the camera close to the opening of the little house and snap. I saw 3 little birds, it took my breath away. The birds are out of the house and having a blast, but the cage is getting a bit small for all 5 birds. I'm very happy to have these little additions to my family of animalitos. So let me tell you a bit about the new babies: (it = he or she) Beaker .. because it took the longest to come out of the house, and it has a black strip over it's beak. Fighter .. because it fights with everyone in the cage. Destroyer .. it tears, rips, peck, and tries to destroy all the toys in the cage. They are the most energetic and playful little things you ever did see. I must go shopping for a new cage for them. Bigger and wider with lots of room to fly around. I will never cut their wings, so they will be free to do as they please in their cage that is. I took so many pictures and videos of them to show all my friends and family, I'm such a proud mamma .. don't you think ^;^
