Hiccup/cough and barking?

Hey everyone! My chinchilla starting doing something odd today- he was sitting on the bottom of his cage (not abnormal) and then would give a quiet hiccup/cough like noise, followed by a series of barks. He does just one of those strange noises at a time, about 30 seconds or so apart. I'll try to get a video of it if I can. My questions are- do chinchills get the hiccups? If so, what do they sound like? And what do coughs sound like? He doesn't have a runny nose or watery eyes, but I'm on the lookout for any symptoms of a URI just in case. Thanks in advance for your help!

Sound like the alarm call that means "HEY EVERYONE RUN AND HIDE!!!!!!". When they make that call and there are other chins they all split and hide.
