If you have the drive and space, you could set up a quail habitat. They are a small social bird that can be housed in your house easily. Three of their eggs is about the same as a chicken egg. They need a low ceiling in their enclosure. Their enclosure can be built with wood and pond and seal. The wood could be and old display case cabinet or from scratch. If you use peat moss and live plants and spring tails and other little harmless bugs, you could turn the dirt. If the bugs aren't ideal, you could just change the dirt out with new dirt. Dump the old dirt in a bin outside and let sit for 6 months and turn every now and then. Then you can reuse that dirt again.
