Backyard chickens in Harlingen, Texas

Yes, backyard hens are allowed in Harlingen, Texas. According to Harlingen's animal-keeping rules as compiled by a Texas municipal chicken-law directory, residents may keep up to 6 hens on residential property, roosters are not permitted, and no permit is required for a compliant small flock.

Harlingen's official Code of Ordinances, Chapter 6 ("Animals"), is codified on Municode, but the chapter's specific fowl-keeping sections could not be rendered as plain text for direct sentence-level citation during this research session (the Municode page loads via JavaScript). The rule summary above comes from a secondary Texas chicken-ordinance directory that specifically lists Harlingen's requirements and should be confirmed with the City of Harlingen's Code Enforcement or Animal Control office before building a coop.

Harlingen sits in the Rio Grande Valley of far South Texas, one of the hottest and most humid regions in the state. Summers are long and intensely hot (frequently 95–100°F+) with high humidity, while winters are short and mild with rare, brief freezes. Chicken keepers here need to prioritize shade, ventilation, and constant cool water far more than cold-weather protection.

In the Rio Grande Valley, backyard flocks commonly face raccoons and opossums raiding coops at night, hawks during the day, coyotes on the urban fringe, and rat snakes that target eggs and chicks. Secure, hardware-cloth-lined coops with predator-proof latches and a fully covered run are strongly recommended year-round given the region's warm climate, which keeps predator activity high even in winter.
