I have a pair of budgie and female budgie havehas laid the first egg on 14 aprilApril 14th, then second on 17 aprilApril 17th, and with a gap of two two days she has laid total 5 eggs so. So my problem is...: the 1st egg has been hatched on 6 mayMay 6th and the other 4 egg areeggs haven't not hatched yet...
Is it possible that left eggs are infertileunfertilized?
