I don't think this is strange at all. My TSC waits a little while before they put the chicks out on the floor. For all the reasons @JacinLarkwell has mentioned. And I used to work at Petsmart, we would hold all our new arrivals( small animals and birds) in the back for a minimum of 24 hours before we would put them on the floor to sell. That would tell us who was sick and who was healthy
