A single breeding pair can produce about 500 mice in about 5 months under ideal conditions. In the wild, their average life span is only a few months. Baby field mice are blind, deaf and bald at birth but mature within about 3 weeks. Females are sexually mature at 4 to 6 weeks. Along with their natural habitat of the fields, they can be found in human habitation including homes and barns.
Fortunately, the Indians know that many fans enjoy entering the park several hours before first pitch, and are willing to accommodate. For a 7 p.m. game, for example, Progressive Field opens at 4:30 p.m., but be sure to line up at Gate C, as it's the only gate that opens this early.
Like most MLB teams, batting practice starts approximately 3 hours  before gametime. There are certain situations, (noon start  following a late game, rain delay) where BP iâ¦s later than that.   Fenway Park's gates open two hours before game time. One person  reported that the Red Sox take the field about 20 minutes before  gates open, and stay out for approx 30 minutes after gates open.
