I realize I am hijacking someone else's thread but our problems are so similar that there isn't really a point in making a new thread.
I have 12 week old standard rex baby that was also acting lethargic, hunched, and staying in place. Considering he stays in a colony style room and typically runs away this was abnormal behavior. Log on to RabbitTalk, find this thread, I give him hay and lots of oats before rushing out the door to buy pedialyte and simethicone gas drops. Come back, most of the oats are gone and he is starting to act a lot like himself again(All in less than half an hour). Should I give him the gas drops and pedialyte anyways just in case? Currently quarantined in a separate cage from the others.
