do this with my canarys all the time ,the first egg is taken out when laid in the morning then every eeg up untill five have been laid then all are put back in again ,so as they all hatch at the same time ,before anyone asks what it has to do with pigeons have done the same with their eggs had them laying about the loft for a month being the longest and still hatched and didn nt turn them every day not to say they dont ned to be though .
