Goldie sat on egg yesterday only to be smashed later on, checked 6.30 this morning and sat on another, fed later and had another look , smashed again, checked Siskin and 4 eggs not 5 now, must be goldie cock I think , but don't want to take him out as he's always been in aviary not cage, put dummy eggs in goldie nest and she's sat on them, next 2 or so eggs I will take out and put dummy's in then put real ones back in hopefully he will have got bored of trying to smash dummy eggs? Any better ideas
