Robert,
...Mine do not eat but very rarely when they are gravid. At about the time I warm them back up the males start mating with the females and the males are not interested in eating. The females will eat heavily during the mating season. After they have been bred for several weeks they will all at once start to look gravid and at the same time the males are no longer courting them and the gravid females go off feed. Many of them do not eat anything for the 5.5 months from the last mating till they lay their babies. Some of them will eat a few small meals after a couple months of being gravid. I do not offer them anything larger than a medium rat while they are gravid. Out of over 90 litters of BRBs I have never had one eat heavily after the breeding season and then lay babies. Make sure you leave the males in with the females for as long as the males show interest in mating. I would keep feeding the one that will eat and also try to get her bred some more if possible.
Good luck,
Jeff
>>I've got a question for you guys out there that breed rainbows. This is my first year breeding Brazilians (though I've kept them for like the past decade), and I was just wondering if you continue to feed your females once they are gravid. One of mine is currently still feeding, while the other is refusing food. She's the smaller of the two, so I thought it might be good if she got at least a couple of smaller food items in her every now and again over the course of her pregnancy. Any thoughts?
