Has she considered quail? They would be better suited to that spare cage she has, and require much less maintenance than an indoor chicken. Most of the same benefits of a chicken - you still get eggs, you could hatch out new quail, some are remarkably attractive birds. And they are small enough that the law would never take an interest if you just had a few of them indoors.Anyways with talking to the talking to the town hall, by law person, to own chickens you need 3 acres of land and since she doesn't have that much... I will be asking the neighbor who owns several hundred acres if we can 'rent' a small piece of land close to the back of my sister's property to build a hen house... He is an older gentleman who seems very nice so hopefully we can arrange something...
