hey there. so i have a pair of lovebirds which got on fine until they started breeding. im not 100% sure on their gender but surely they are female and male as their breeding behaviour (intercourse) showed so. also the suspected female looks bigger, her droppings are bigger and filled with water and around her entrance it seems bigger as if shes preparing to lay an egg. im new to this whole lovebirds being pregnant situation so i want to ensure everything is okay and this is normal. so my question is, does it seem normal for the 2 to become aggro towards eachother? my 'male' lovebird seems to be attacking the female everytime she tries to enter the nestbox. they fight as soon as she goes in until one of them comes out. they're also aggro towards me and normally they never are. i purchased them 2 months apart from the same breeder and purchased them tamed so usually they would roam the house and such but they're obsessed with the nesting box. is there anything i should be concerned about? anything to do or contact the vet just incase? thanks
