This isn't a lot of info to go off of but I will tell you that Baytril makes them not want to eat, and also causes them to get very dehydrated. So what you are describing sound normal to me for a cham on Baytril. You just need to make sure that he is drinking and you are providing enough opportunity to drink. (I have given twice as much water as Baytril by mouth once I had the mouth open, however, you have to be careful they don't inhale the water) And try to find something they can still get excited about eating. For me that something has always been superworms. I know they aren't the best nutrition but the can get the cham through a hunger strike during Baytril treatment. Monitor the chams fat pads and as long as they are still not sunken you should be fine. If they get really sunken in you might want to think about feeding ground up bugs or placing something in his mouth when you are giving him his treatment.
