About Us


Rosita Ranch began as a hobby for Stonyford resident, Jennifer Diaz. Jennifer began to raise her own chickens for farm-fresh eggs in 2008 as a sustainability project for her and her family. As her passion for chickens grew, she realized her chickens were producing more eggs than she could handle. In 2012 she began to sell them to neighbors, and eventually started selling them at the local farmer’s markets. 

As her eggs grew in popularity among customers and Colusa County residents, she started the process of getting her eggs and herself certified. Now, almost 5 years later, Rosita Ranch appears at their home base in Stonyford, the Colusa Certified Farmer’s Market, as well as certain Colusa County stores. Jennifer also regularly donates eggs to the Williams Family Action Center. 

“I am proud to be able to provide a healthy local product to the community.”

Jennifer’s love for farm-fresh products took deep root, and she now manages the Colusa Certified Farmers Market during the summer months in Colusa, and has started a “Farm to Fork” dinner that features locally grown and raised products. She has also grown her personal business to include not just eggs but seasonal fruits and vegetables as well.
