Welcome. A friend, I haven't seen in a couple of years, has some small, exotic chickens, she keeps as pets. She even has diapers for them so they can be inside some. She lives not too far from downtown Dallas, in a big old house with huge yard. (But lived in a two story duplex, small yard, for several years until they decided what to do with the big house. They restored it, eventually.) You can have chickens and other "farm" animals in city limits but no roosters or cloven/hooved animals. Sweet babies they were.
BTW... she and her husband have known DH since Medical School, late 1950's but they just hooked back up about 10 yrs ago. When I went to visit her, first time, in her duplex, she was pretty amazed I didn't think she was weird keeping chickens as pets.
