In Pennsylvania, assault is a crime that can be a misdemeanor or a felony. A person commits an assault when he inflicts (or attempts to inflict) a physical injury on another person.
When measured from conception it is about 38 weeks. An embryo is the developing offspring during the first eight weeks following conception, after which, the term fetus is used until birth. Symptoms of early pregnancy may include missed periods, tender breasts, nausea and vomiting, hunger, and frequent urination. Pregnancy may be confirmed with a pregnancy test.
As has already been mentioned, the pregnancy will last about 35 days, although some will give birth in as few as 30 days and others have been known go as long as 46. Most, however, will have a normal 34 - 36 day pregnancy. If the female does not give birth by her last expected due date, give her at least another 11 days before assuming that the breeding wasn't successful. Your expectant mother will require a nest box at least one week before her first due date.
