Hi there everyone. I am Deri and I need some advice on my ringnecks please. I have a male and female and the male is adorable, very loving and gentle, the male started off loving and gentle when I was hand rearing her and then after that she became a maniac and just bites always. I then separated the two as she was such a bully and I put Mumbles (the boy) in our avery outside and Blu (the girl) stayed in a cage in my lapa, it just became too much of a noise keeping them inside and we all suffer from sinus. Anyways, I then decided to put Blu in the avery too as I felt she was lonely, but she wrecked everything, all the nesting boxes (I have red rump parakeets too) so now they have nowhere to nest. And Blu is just a huge bully. After wrecking the boxes, she moved to the ground and dug a hole to china, her bunker, which I have never heard in my life before. And she is even more aggressive than before, she is like a snake, she beak butts whoever or whatever walks past. She has even dug the hole right through so she could escape but she doesn't. My daughter has since discovered 2 eggs, and then I discovered a 3rd egg on Monday??? I am so confused. Can they lay infertile eggs?? Why I ask this is because I don't think she would allow anything near her, let alone the male as a mate, she is too full of nonsense. Now I am worried, as our rainy season is going to start soon and her bunker will get flooded, haha. Shame. Although I really do not want babies. I have enough pets to feed. But what is this underground bunker part all about? Hope to hear from someone soon. Thanks & Regards
