well i have 2 loves birds a male and a female and their outside with a big cage we made for them she has her nest box at the at the bottom of the cage.the female had layed her eggs like at least 3 weekks or 2 and i was wondering because they stay in the cage the whole time and i know that at it takes like 25 days for them to hatch but what if it passed and the lovebirds still stay in the nestbox? what do they know they aint going to hatch or they know that it may take longer
