She is indeed Agouti carrying husky, it comes through in different strengths in different hams. My Rolo's mum Daisy was a pure Agouti with her line stretching back for years, I bred her with Dasher who was a Husky, and as expected all babies came out Agouti. When they were little they were all very chocolatey with dark faces like mum
