In most cases our females are absolutely ravenous after laying! I'd give it a week or two between offerings, though. Let her get good and hungry. Another thing to consider is did you clean her tub/tank VERY, VERY WELL after she laid? If she still thinks she is pregnant or smells her eggs she might not eat. I've had this happen with a few corns before. Also if there are other gravid females around it might be putting her off. I would start simple and clean everything, get her away from any other gravid females and give her a little time to build up an appetite. This is of course provided everything else is spot on husbandry wise.
