Moochie, I don't know how many birds you have now or even if you are still wondering, but you could go around putting up flyers for fertilizer from both your fowl and goats. A lot of people look for organic fertilizer for their flower and vegetable gardens. This would give you a little extra income. If that is truly a pic of your birds then you could also offer feathers to people that do crafts. You could also pet sit for people that go on vacation or have to be out of town for a while. You could also offer eggs to your friends, I sell mine to people I know at $3.00 a dozen and they love them ( I also bought my own unmarked cartons ), but since you seem to shy away from people I don't know if that would be any help as you may not have to many friends. Not trying to be mean in anyway just logical.
As far as greens and roughage for the goats, go to your local super market (not a big chain store, a locally owned store) and ask if it would be possible for them to save you the produce that they are going to throw away. Be sure to go on a regular basis or they will stop doing it for you. I do it. What our chickens, ducks, geese, guineas and turkeys won't eat we give to our goats, they especially like oranges and it helps keep them hydrated in hot weather. Some of the harder produce, like potatoes has to rot before the chickens eat it sometimes though, all our birds especially like mellons and cantalopes.
I also have a Rock Dove ( pigeon, I don't like that word to me somehow it is derogatory) that I raised from 4 days old squab, he is one of the best friends I have ever had! I could not stand shoving that tube down into his gullet like everybody said to do, I was afraid of hurting Baby, so I fed Baby from my mouth. He actually asked me to by rubbing his beak on my mouth. The reason this happened was, I was afraid I was going to lose him and I reached down to kiss him and tell him I was sry that I didn't know what else to do. At 4 days old he showed me how to save his life. That to me is amazing, I know people that aren't that smart! Today he is a healthy and handsome 1 year old, he goes and comes as he pleases in and out of our house, always sleeping in the house, Baby never leaves the property, although he can. He has never seen the inside of a cage and never will. He is free to do as he chooses and he chooses to stay with us. I have never seen a smarter animal, he has such a wonderful personality!
Well, that was way off the subject, I apologize. I wish you the best of luck and hope you find your niche Moochie!
