Color western Ranch

A western movie's name?
Now I watched that movie on the TV at 2 am last night and I didn't catch it from the beginning. Problem is I don't remember any names, but do remember the plot quite well. So here goes: it's a comedy western and it's old. I mean really old, 60s or 70s old, but it's still a color movie (or was colored). 5 women come into a small country town and buy a ranch. Their leader presents herself as a doctor (the real doctor whose ranch they're buying is a man and this woman is notorious wanted criminal as the viewer finds out later), and a local gang from 5 siblings - a female leader and 4 brothers, have their eyes on the same ranch, knowing there's oil in it. The conflict is that they want the newcomers off the land, but as the plot goes the brothers fall in love with the 4 women, and the two fractions ally. There's a goofy sheriff fitting somewhere in here. At the end the oil is found and they rob happily ever after.
A local Bulgarian one so it won't make a difference if I remembered it. XD
