I've found that an oft-fed (tubed) kid won't suckle b/c they don't get a chance to get hungry. As she gets stronger and you space out the feedings she may well figure it all out.
We use the red pritchard nipples (TSC usually has them though they are really pricey considering I can order them through Jeffers at a fraction of that, but when you need something fast...). After being on mom, you will have to put the nipple in her mouth and hold her on it to get milk in her. Be prepared for a mess and a bit of frustration but in a week, she will be much easier about taking it. Letting her get hungry will help.
yes, the pritchard nipples are great for the smaller goats. put something sweet on the nipple, and then wait till she starts looking around for food. i hate to tube feed, irritates the esophagus if done too often
We use pritchards with out NDs and we bottle feed exclusively here--she is only resisting because it is new to her. I would not try to put her back on mom at this point and would just keep working on the bottle. I am sure it is frustrating but she will get it. Use a finger to prop open the corner of her mouth to slide the nipple in, then cup her nose around it with you hand. You might even gently squeeze a few drips in to get the taste in her mouth and trigger swallowing (not too much though--don't want her to aspirate it). If you can cut out the tube feedings and try to stick to three feedings a day, 4-6 ounces at a time, she will start taking the bottle eagerly in a few days.
I've never tube fed one, but when we've had weak kids we would just use a syringe to get colustrum in there mouth and watch for them to start swallowing.
That might be an interim step you could try, just take a syringe and squirt a small amount in her mouth to get the swallowing action going first.
