Yes they do... Ask soon as you walk in they are normally pretty helpful when you ask them a question...
I believe I've seen decently sized bags of bird feed in the store at one point or another, probably like 10 or so pounds. I do know you are able to kind of make your own blend as well in the back and I think it's pretty cheap. I stay more in reptiles and aquatics, so I hope I was able to answer your question some what.
