Can an 8-week-old Buck impregnate 11-week-old Doe?

No, an 8-week-old buck cannot impregnate an 11-week-old doe. Bucks typically reach sexual maturity between 6 to 12 months of age, while does reach sexual maturity between 7 and 12 months of age.

Bucks and does must reach a certain minimum bodyweight and age to reproduce, and it isn't recommended they are used for breeding until they are at least 6 to 8 months of age. Breeding too young can lead to various health problems, including birthing complications and poor-quality offspring.
