Ok so this probably sounds really weird but I can hear the strangest noise coming from both of my chicks! It sounds exactly like a light bon fire or if you were sauteeing something in a pan or boiling water. Its really hard hard to describe but its a fuzzy/crackeling noise. I cannot tell where its coming form, but if I would have to guess, I would say there little behinds! Its decently loud where I can hear it a few feet away. What the heck is it?!?! Its so weird. Their poo has been extra liquidy these past few days too.
