Hi there. I'm a newbie here and I need yall's help! (Also sorry for any confusions/mistakes, English is not my native language).
So 3-4 months ago I bought 2 lovebirds (from a pet shop), they didn't know their gender and I didn't take any DNA tests because I don't know if I can really afford that ( I am a broke art student lol).
Anyways, they got along quite well and I think they bonded. 2 months ago one of them started picking on paper and branches and gathering them in its wings. Later, the other one started doing this too but wasn't as successful. And then we saw them "mating". We noticed that the blue one was on top every time and the green one were more and more invested in nesting materials. So we thought the blue one is a boy and the green one is a girl.
Until now, they still haven't had any eggs. But today, as they were "mating" again (or trying to idk) they switched it up!!! So during like half an hour they would try to mate and switch it up, they would get on each other's backs back and forth.
So now I am really confused. Are they both males? But they put nesting materials in their wings. Are they females? But would they get on each other's backs if they were? Or are they actually a heterosexual pair? Because in that case I should be careful especially if I want to care for eggs and newborns and etc. I have only had budgies, but they never mated/laid eggs so idk what to do. I tried to put a cardboard box to see if they want to build a nest there but they chewed on it until they destroyed it completely lol.
I will look up how much does it cost to do a DNA test though, but if yall are bored and wanna share your opinions I will gladly read them all. Thank you!
Here are the babies!
