Putting four chickens in the yard seemed like a good idea to have cheap eggs. Bird flu just changed the rules of the game
From November 13, 2025, there is no poultry farm in the country that can be outdoors. With mass confinement, the Government wants to contain the spread of the H5N1 bird flu. And it makes sense: so far this season, 14 outbreaks have already been recorded in poultry, several in captive birds and dozens in wild birds. The problem is everything that falls under the radar. “What do I do with my chickens?” In Spain, at least from 2024, all chickens must be registered. And yes, that includes ‘self-consumption’ chickens; some animals that, according to the data, they represent only 0.77% of the census (but all experts know there are many more). A report from El País from the spring of this year confirmed that “the figures do not reflect reality and that a large part of self-consumers have birds (especially the ISA Brown species) without census.” This has meant that in a context in which self-consumption does not have inspections (and lives unaware of animal health regulation), the doubts and risks have grown exponentially. As Cristina García Casado explained in InfoLibrethe question most frequently asked by veterinarians across the country is “what do I do with my chickens?” And the answer is very simple: confine them. Because the regulations do not understand sizes: a backyard chicken infected by contact with a wild bird can be just as big a problem as any other type of chicken. Or maybe more. After all, the European authorities they continue to qualify the risk to the general population as low; but they raise it to low-moderate for people in direct contact with infected birds or contaminated environments. Having unmonitored poultry increases the risk to the “civilian” population and if we are realistic we will recognize that they cannot be monitored. The problem has names and surnames: at least when it comes to the flu, all those domestic pens have the same sanitary requirements, but much less infrastructure. The ‘boom’ of homemade eggs. We must remember that this does not happen in a vacuum. The truth is that in recent years we have lived a real ‘boom’ in self-consumption chickens. It is the confluence of the “happy chickens” movements with the response of many citizens to a price that does nothing but go up. According to the National Institute of Statistics, have gone up 15.9% so far this year and, according to the OCUthe growth has been 105% compared to 2021. And, be careful, we are not talking about a luxury product. We are talking about what may be one of the proteins cheaper and more accessible of the world. Faced with this ‘ovoflation’, the accounts are clear: “a hen costs about nine euros, it is easy to raise and maintain with fruit, vegetables and feed, and it lays an egg every 25 hours.” How can there not be a problem? What to do if I have a chicken coop for self-consumption? If we are in that situation (or are thinking about setting up our own domestic corral) there are some things to keep in mind: Whether larger or smaller, the corral must be registered in the REGA (General Registry of Livestock Operations). Implement confinement and biosecurity measures: separate chickens from any contact with wild birds; control inputs and outputs; record all changes in a log book. Improve cleaning conditions, more frequent bed renewal and tightening daily management protocols. Introduce wellness programs to contain the problems associated with a sedentary lifestyle. But, above all, be extremely vigilant. There are many warning signs (apathy, drop in production, high mortality or flu symptoms). Therefore, it is best to be alert. Anything can happen.
