There are some things going on, depending on the species, but essentially.... For example, in Quebec right now, we've had several swine farms that have been transformed into duck farms. That's been done by whomever has the means of doing it, and there is no consideration for whether it is wise to do it in this particular place. We've had situations where you have duck farms now that are very close to egg layers and turkey farms, and it has resulted in more cases in Quebec of high path AI, as an example.
People can build a new farm and a new barn within 100 metres of an existing farm, as long as they respect the regulations for the water table and all that. There is no consideration for the risk represented by building a new facility so close to another one, so that's problematic.
