I haven't noticed any but I haven't been looking for them either really. I have slacked on dusting him lately.. Is it supposed to have like a hard knot under it? It's totally dry and kinda tough feeling. No oil comes out of it when I touch it and I notice he isn't utilizing it either.. he normally will preen all the time.. hes probably somewhere between 2 1/2 and 3 1/2? Just a guess though. I've had him for almost 2 years and when he showed up he only had nubs for spurs but he was already huge. He is extremely patient with me and he loves all kinds of lovin' so I'm pretty certain that it's painful to him. I have this photo, a better one, from earlier. And then another of how scraggly he looks lately. Although, we have been going for dips in the river recently because of the heat.. also, do you know what breed he is? He's feather footed and weights probably 8 lbs.. Thank you for your time.
