Hi all. One of my 4week old babies is very lethargic, wings down, eyes droopy etc. At first I suspected cocci, but upon inspection, it's crop is very large and full feeling. they've been on chick starter with minimal treats (yogurt, hard boiled egg on occasion, sometimes a piece of fruit or veg) acv in water, etc. Not sure if it is sour or impacted at this point. Still has an appetite, but I've separated it and just have yogurt and water in there now because I don't want it to eat if it's crop is so full. So do I turn it upside down and massage in order to get it to regurgitate?
