My 1 year 2 month old doe appears rather lager than her twin. Before I got them, they were kept with a youn buck about a year old. The twin does were born on Easter last year, so I dont know if they could get pregnant yet... they have not had access to grain exept for a few corn chips. Any help will be appreciated. Thanks! First pic is the one I think could be pregnant, the 2 is her twin.
