Anyone know if this is loofah? It grows where I planted some seeds, but I don't know what they look like.

Looks like it to me.

I FINALLY got some growing. Hard to keep the chickens from eating it, and don't have room in my garden cage.

I bought a package of summer squash varieties, AND winter squash varieties. This looks like luffa to me. Isn't luffa a gourd not a squash? I would not have planted luffa seeds in the veggie garden. Anyone agree it's luffa? Not the best tasting "squash", but very healthy.

Nice looking fruit.

Consider changing the white balance setting on your camera to "Auto" and then your pictures won't be blue.

I keep doing that, and it changes back.

I inspected your image and it seems to be changing the white balance to manual. It might be a setting in your device somewhere.
