Hello, my flock consist of 12 hens and 1 rooster. My young rooster started crowing about 3 weeks ago now- the first few attempts were funny, but after he got the hang of it- his crows were smooth and strong. Recently he started crowing very oddly, not smooth or strong. When he crows it sounds like he runs out of breath to keep it long and strong crow. Apart from that his odd crow sounds shaky, like if maybe he needed to drink some water to clear out his throat. Which I provide clean plentiful water. Rhapsody is the word for his odd crow. His comb and wattle are bright red and he still is active with the flock. He eats and drinks and gives his hens some lovin. So I'm not sure what's going on with his crow... I did read some articles about 'impacted crop' but I haven't come to conclusions if this could be a reason he is crowing oddly and weakly. Any suggestions?
