Sorry to reply so late, between work and the Holiday I haven't been able to reply!

I think it's just his coloring, honestly. I haven't been able to look up "Red Leg" symptoms properly and I won't be able to until tomorrow. I am actually in a rush right now, but I will update you further and answer more questions tomorrow. He has no symptoms of being lethargic, yawning, or anorexia from what I can tell. He eats extremely well and acts like a normal ACF.
