Do you want to grow your lawn from seeds? It is an affordable option, and for smaller lawns, this is a good option. When I first decided to buy seeds for my lawn, I purchased the most expensive and top-quality grass seeds. I sowed the seeds and waited for days and then weeks for the grass to grow. However, the grass only grow in patches, and I had to reseed. My neighbor, who was watching me struggle, told me that it was the birds causing this problem. I asked him, do birds eat grass seed? And he answered yes. Here is what I learned about birds eating grass seeds.
