This is a clear and concise account of a straightforward method of training that is commonly used with dogs, but which apparently also works with chickens. I intend to try it with my own chickens, who I currently get to stand on scales by letting them inside one at a time and dangling a mealworm over the scales, which works, but then either they are very quick on and off or they are liable to jump up to try to reach the mealworm, which wrecks the reading; this method looks much better.
The article is appropriately illustrated with examples and photos, and is well written. It would be useful to add, in a reference section at the end, the bibliographic details of the work from 2005 cited in the opening paragraph, so those who wish to follow up could do so.
