Can anyone give me a reason why my 3 female phants keep laying infertile eggs.I presume they are dud as they usually lay them on leaves or wood,I did have some laid under moss once but have lost one of my 4 females since then,even then I was unable to sucessfully incubate them, all of my phants are wc so could it be they are to old it is impossible to get cb youngsters here in UK. THANKS
