I lived in a very strict HOA in Dallas before moving to Corpus. Most HOAs cant stop you from altering your house as long as you get the required plans approved by the HOA board. I think that is to keep people from building something weird on top of their house that makes the property values drop. I modified my garage and made a room out of it..as well as built a greenhouse in the backyard on a zero-lot-line. I say keep your hens in a dog kennel or something like that. There is a difference between livestock and fowl/poultry. If your HOA has a pond with ducks living in it..they are breaking their own rules. Since you are already at this point and know who the complainant was..why not just go talk to her. Keep your enemies close..
Good Luck...
