My son recently got 2 ringneck doves, a male and a female. We've had them for about 2 weeks now, and tonight the female laid her first egg. The problem is, it looks like she just dropped it from where she was sitting on a perch. I found it directly underneath her, smashed. We had 2 nesting boxes ready to go in the flight cage before we brought them home. One was a round Tupperware dish, the other a cardboard box cut to what I was told was the correct size (6"x4"x2"). We laid out a variety of nesting materials-twigs, hay, strips of paper. When they showed no interest in creating a nest, I put a few pieces of hay, paper, and feathers in the box. Still nothing. Tonight I cut another cardboard box and secured it to a high perch, thinking they might prefer to nest off the floor. Does anyone have any ideas? These are our first birds, but they seem healthy in every way. Lively, curious, active. They get most of the day outside of their flight cage in my son's room. How can I get them to nest? PS- Any info on the appropriate amount of calcium to provide an egg-laying female would also be appreciated!!
