I know where that Wildbird Store is.
I usually go to the Tractor Supply in Katy.
Get a bag of the safflower seed, it will save you plenty of money and time refilling the feeder. Filling my 3 feeders with black sunflower seed had to be done every other day. And then I discovered the white safflower seed. Maybe every week or 2 and the birds love it and they don’t have to wait for the squirrels to leave.
