The most notable characteristic of the Ruffed Grouse isn't how they looks -- it's how they sound. In the spring and a little in the fall, the male ruffed grouse beats the air with his wings to make a loud drumming sound.
expired test strips are NOT reliable. most strips have an expiry date over 2 years from the date of manufacture...... that's a long time for them to be 'sitting around'. as for e-bay........
Once we determine how long after manufacture the test strip performance is valid, say 18 or 24 months, this information is used to calculate the expiration date that is applied to the strip vials at the time the strips are made.
