d'Uccle breed bantam roo. Lethargic. 'Puffed up' body language at times. Appears to be 'sleepy' and stationary when rest of flock are actively foraging. Feces appears normal, if somewhat dry. Comb/wattles are PALE, and have been for over a week. Comb does not appear 'scaly', per se. No other visible markings, lesions, scabs or swelling. Not a serious loss of appetite, yet somewhat thinner/emaciated regardless. Doesn't drink as much water as he probably should. We have treated for coccidiosis for the past 5 days, putting a considerable dose of Corid in his water. Has moments of 'normal' behavior and energy, followed by bouts of the aforementioned. We're stumped. Help.
