I am slightly concerned about the possibility of trade deals with the US bringing in bleached chicken and meat from cattle treated with hormones to promote growth. It might never happen, of course, but the local butcher has closed because the shop had not make a profit for some years. Eating quality meats from local farms made sense to me, but not to many others in the area. I have been considering keeping quail, and rabbits - both quiet inoffensive types of animal if there was to be a relaxation of the regulations on animal husbandry. Pigeons would be another possibility. I have limited space, and live in a built up area. Are there any other possibilities? I believe guinea pigs are edible.
