lol i actually get that alot from aussies! LOL they always are like you WANT emus? lol in i live in central Pennsylvania our winters can be harsh and our summers HOT and emus do REALLY well here! you only need like a three sided shelter for them and there good to go lol 6 foot fences are needed since they can JUMP really high....i have them as more of a ....pet / livestock. i have 2 females so i need males but when they are breeding ect we plan on selling eggs, chicks, adults, ect just for extra money in the pocket then to raise acouple for ourselves to fill the freezer! predators are not really an issue aslong as you have them properly fenced in we have coyotes which is somewhat the same thing as dingos and if my emus ever got out i would actually bet my bottom dollar they could escape form them! thats basically the only real threat to them as ADULTS! now chicks and young ones foxes, possums, raccons ect but like i said if there secure and safe your good! money wise eh.....chicks range for 100 dollars...eggs between 25 to 30......adults can go from like 600 to 1000 .....and pairs up to 2 thousand dollars... getting into emus is expensive upfront! but once you get off the ground you should be alright. there not a get rich quick thing but they can and will bring in some extra cash. OR make good pets lol
