She has straw bedding (cleaned yesterday) and a lot of hay in the feeder. Can i give her more straw if there won't be enough? Wouldn't it stress her?
If she's used to you being around (and by now, she should be), this shouldn't be stressful for her. Or, look at it this way, if she is so high-strung that this would be too much stress for her, she probably will never be a successful mother, since she will be constantly going crazy over nothing.
