It is natural that you are worried about your budgie, there are some things you can do to help him. Firstly is it possible to post a picture of him and his poop?
Cover his cage on three sides, use a hot water bottle or other heat source to help him keep warm when sick budgies expend a lot of energy keeping warm. Feed him some egg and biscuit mix or millet, these are good conditioning foods. Hold off on greens as that makes poop watery as well.
Get some probiotics, having these things on hand is a must when you have birds in case they do get sick. Also some apple cider vinegar added to the water, just a couple of drops but it must contain Mother. this is a natural probiotic.
Can you hold your budgie? if so hold him up close to your ear and listen for any noises when breathing, crackling or wheezing or squeaking sounds. if any present place his cage in the bathroom and run hot shower to make steam or use a kettle near the cage under the blanket like a tent. If you have some eucalyptus oil add a few drops to the water if doing the tent method. this will help the airways.
