If so they are lobster roaches, which make an excellent feeder. They are incredibly prolific breeders and give live birth as well, but they are a little on the smellier side for a roach (still not as bad as crickets) and they can climb smooth surfaces such as glass. We can discuss more in detail if this are the woodies in question = )

Edit: Picture fail... wayy too small haha. Go ahead and google 'Lobster Roach' or 'Nauphoeta cinerea' and take a look at the pics.
