Other nesting activity

I have provided nesting boxes to both my Bourke Parrots and the trio of Indian Ringnecks. Not expecting much from either as the Bourke female that consistently lays eggs and incubates but never hatches chicks and I only believed that I had one Indian Ringneck female (Creamino "Milly") and she is only a year old and too young however my Blue Ringneck "Boe Boe" that I was believed to be a male from it previous owner is actually female!! She has laid one egg but she is still immature a results may not be optimum.
