We call them spent hens, just older birds really. Depending on the area of the country, there may be demand for them as food processing but it requires specialized equipment. In Atlantic Canada, there is a large market from the fur industry for spent hens.
We have also supported several projects on looking at methods to increase the value of the spent hens to the industry and the processors. We don't want to just see them destroyed; we have environmental issues with that, so we have supported projects looking at producing high-quality glue from spent-hen material. That's been a very successful project we expect to move from our research efforts to industry to the processors and developers within the next couple of years. That is a major issue we've put a fair bit of effort into dealing with.
