Sounds like GI stasis. I would get some fluids in him. Maybe some pineapple (Fresh). If you have any probiotics like yogurt or benebac I would get that into him too. He may need to see the vet. GI Stasis is pretty serious if that is what his problem is.
Thanks. It does sound like gi statis. i have given him simethicone, massaged him, given him yogurt, and let him run around the back yard. He is still pooping a bit, but he didn't eat last night or the night before. I will keep on top of this and hopefully he will pull through. he is a meat rabbit, so a vet is out of the quetion.
funny, when I was seraching for what might be wrong with him, I got nothing. Now that I know nd look up gi stasis, I get lots hits.
