water bowl wrapping

Ok, here we go. I keep only 7-8 adult ball females. 4 adult males. All bred as usual this past winter and spring ( Dec-Mar). 1 didn't take( she is back to eating and no ovulation or signs of anything other than not bred),2 laid, 1 to lay yet... now... 3 proven females. They ate like pigs for about 30 days, went off feed in late March. They are all 3 wrapping the water dish.. but there is no sign at all they are carrying eggs. Thin in the belly area, Never saw an ovulation.. due to youngsters coming up, was going to sell 2 of the 3.. after they laid.. but all refuse food, wrap water dish.. and are proven.. Temps are 90 warm side, 85 cool side ( Sterlite 41 qt containers). Hate to sell them and then they lay.. none of my females have ever read the book about laying eggs.. have had some go over 55 days after the shed before they laid...
What would you all do? These are morph females bred to morph males...
