I understand what the last few posters are saying, but I do feel like employees should be expected to know the basics -- which breeds they're selling, what purpose the breed has, whether or not they're sexed, and what basic items are required to care for them. Yes, they only carry chicks for a few weeks, but during those weeks they are a featured item. That means there will be a lot of customers coming in specifically for that item, and there should be some formal preparation for the staff to deal with basic questions or at least refer customers to someone who knows the answers. I've worked minimum wage retail jobs, but I still was expected to learn product details and answer customer questions.
I actually emailed TSC this morning suggesting that they advertise for and hire seasonal help for this time of year, people with chicken experience and knowledge who could make sure that customers get what they're looking for and are prepared for what they get. Even if they just brought a local "chicken person" in for a pre-Chick Days store meeting to go over some basics with employees, it would help.
Yes, ultimately the responsibility to do prior research and preparation lies with the customer, but I think everyone knows that a good number of chick purchases are impulse buys. Does that mean that TSC has no duty to ensure the welfare of the animals by making sure the customer knows what he or she is getting into?
