My RRI rooster has been staying behind in the coop. I felt his crop last night and it felt chunky - like a bean bag. He has been hiding in the corner of the barn this AM. He eats and drinks fine. He has been having issues with mites, and I fear they might have progressed into the larvae stage. How do I tell if he is 'impacted' in his crop or if those were worms? How do I treat with Wazine for one bird? (he's HUGE - and has a hard time dusting himself - he's a bit older, and all 'thumbs'). Will he get depressed if I isolate him from the flock? Please help! He's the hero of our yard. Thank you.
