We have only had these birds for 2 days and both mornings we have woken up to an egg like this. Both days they are found under the perch, so no question why its broken but wondering about the soft looking shell? We were told the 2 older birds are about 6 months old but I suspect only 1 bird is laying as both eggs we have had look like this. Is there a way to train them to lay in the nesting boxes? Is there a way to find out which of the older birds is laying the egg?
