I have a little Booted bantam cockerel, seven weeks old, who was a single chick from a bad ebay batch. He lives in the house for now and is still on chick crumbles with some grit added until I start him on grower soon. He wears a little homemade nappy. He seems healthy and happy but I can't help noticing he is very smelly! I've had a house chicken before and never had this bad smell. It sort of emanates from his face and also his poop seems particularly malodorous. Sort of a sweet stink. I've experienced enough chicken poop to know it doesn't smell normal. Could he have a recurrent mild form of sour crop? Is there anything I can give him to improve this? He eats and drinks fine and his poop LOOKS normal, plus his crop empties overnight and doesn't feel squishy like I've heard sourcrop. He's just a stinker! He's been this way on and off for weeks.
