[cobirds] Unidentified large gulls/Weld

Hi All!

I stumbled upon every gull in a field in Weld county, just west of Ault on CR 33.  There was one very large white gull. Could it be a Glaucous, Iceland or albino gull? In the photos, there is also a very large brown gull. Could it be an immature Herring gull?
