Peppy is now happily sitting on dummy eggs at about 20 days. I was worried because they are quite a bit larger than her own eggs but the next size are budgie ones. Anyway I was wondering if leaving them in the cage would discourage her from laying another batch which seems to happen about a week after I remove them. Any suggestions welcome. I have consulted a vet who was happy to research hormone treatment but it is not something he has used before.
