Hi Everyone, I need a diagnosis! A few weeks ago I had quite a few of my flock get really water-balloony crops, get weak and die. Not everyone that had the watery vomity crops died but everyone that died had the gross squishy crops. There has been zero change in the feed, I feed a chick and grower crumb. I fed a full panel antibiotic and electrolyte to the gang. Everything cleared up. I scrubbed down the feeders/waterers thinking waterborne/food borne. The booster with penicillin and neomycin was a last ditch effort. It seemed to work. Which would rule out the cocci as all signs point to antib's being useless against it. No symptoms since, everyone is thriving. Until now. I've brought in a few new birds, about 4 weeks old. They have been vaccinated for ILT and mareks. They now have the exact same symptoms as the others. Squishy watery crops that ooze when you pick them up. Weak and light (underweight) when picked up. I have had them for a week!?!?! WHAT is going around my coop? It's not cocci/mareks/ILT/parasites. What avian virus is this????? There is no runny eyes or nose or anything overtly respiratory. Just squishy gross crops, huddled, weak, then dead or back to life and immune. 4 week olds don't all suddenly get sour crop at once so lets take that off the table. They re all eating commercial amprolium med starter. is there a Doctor in the house? Oh also by the way NOTHING is available OTC here like it is in the US. We have peni/oxytetra/neochlor. And amprolium only in feed. GAHHHH !!!!!
