I spent some time last night palpating my girls and you can really tell what stage they are in. One girl I could feel 6 or so nice sized eggs, so her due date (30 days past POS) of 5/1 is right on. Another I felt 4 hard golf balls, so I put the male back in and sure enough, they are locked this morning. It is easier to feel eggs in the 1500-1700gm girls. My largest female, Bertha, is 2700+ and she is showing all the signs of being gravid, but I can't feel anything....
