Help me out green thumb bees!

We've been in our home for 3 summers and we're finally starting to tackle the outside. Probably 65% of our lawn are weeds. I'm on a mission to choke them out.

What are your best non conventional, can't find In a basic Google search, tips for growing grass?

We will be overseeding and growing new grass with top soil + compost in certain areas as well.

My other big problem is the birdies keep eating my grass seed! 😒 I'm thinking if I mix the grass seed with soil that should help? We have soil that's heavy with clay in the NE.

Thanks!
