Dont take the eggs away yet, my loves just had their first clutch, 8 eggs, only 2 hatched, they were way over due, i think encubation is relative to time spent sitting. my hen didnt spend the required time sitting, so they were late and only 2 survived.
but they are doing good, i live in dry utah, and didnt mist my eggs, so that may have contributed to my problem also. if you ask these questions in the love bird forum, the experts will give you lots of help. read my threads, "ok heres the story" and "pulling chicks" in the love bird forum. the knowledgable folks answered all my questions there. if you read those threads most of your current, as well as, your future questions are already answered there. dont give up on your eggs for a couple more weeks, that will give her time to get bored with them, and move on with her life, and it will give the chicks a full chance at birth.
also, are you sure of the sex? if you have to hens you will also get infertile eggs.
