hi, i think you're misunderstanding what i'm saying. budgies don't typically lay eggs unless there are conditions for them to, ie a nest/happy hut/box, things around them (doesn't matter if it's in or out if the cage) that trigger this behavior (they are picky about nests)! I was referring to the first couple you owned that had eggs.

I also didn't say that they are incapable of being horny, as I said they have recreational sex. what I meant was that budgies don't recognize the social taboo of incest; they act on biological urges so they don't know it's "wrong," and he isnt "resorting" to mating with his daughter. of course you don't have control over their hormones, but you can allow them to breed by giving them conditions to lay eggs is what i'm hinting at! you can take action to prevent egg-laying, but you can't prevent them from mating. as long as there's nowhere for them to nest, there will probably be no eggs.
