I got my chicks from the store and over 3 days, one has gotten labored breathing overnight. Its sister has no problems, they are dramatically different in weight. It will occasionally drink, eat very little and when its outside it manages to keep up with its other sisters. It sounds like a song bird whenever you grab and excite it and it gasps for air, every single breath. It looks like its suffering. Occasionally it will sneeze but it won't help. The only time it stops is when it sleeps, even then it moves alot when breathing. I've checked down it's throat, felt along it, etc. Nothing. I've tried giving it things like quinoa and small bugs and it sticks right under its lower jaw, I manually pull it down. Please help me. It's been 2 days and it hasn't gotten better. I'm concerned about it not being able to eat on it's own. I hear a slight crackle in its breaths, like bending a hair clip. It looks very sad.
