Help! Recently my 5 day old chick had an air bubble appear on her neck between her head and wing on her backside! (not her crop). I’ve read several posts on here to deflate it but i was worried it would make it worse or kill her so i left it alone. others have left it alone and they survived but unfortunately mine didn’t. i woke up the next morning and my poor chick had passed away. Does anyone know why? I want closure but i can’t without knowing why, how, when, or what killed her. Did she have a heart attack? And what caused the bubble? Thanks!
