Tractor supply has a good selection of chicken related things, if you have one nearby. I've found SS to be hit or miss and I don't very often go there. Now that TSC has chickdays they are fully stocked up for chick and brooder needs, but you'll probably find more empty shelves at the end of the weekend. Fridays I would think would be a good day to find supplies as the stores would have stocked their shelves for the weekend chick buying frenzy.
