I got mine at $18 each, they will lay about 150-200 eggs a year and that easily covers what you get from woolworths coles. I haven't bought any eggs in a while now. Feeds are like $20 for 20Kg and they last a very long time. They will also feed on weeds, grass, insects in your backyard. After 1-2 years, you can use them for meat. Again, you have to check with your local council. In general, if your neighbours don't complain you'll be fine.
Yah lah, bunnings. You should really try ebay, a lot of cheap stuff there. Look for sellers with high rating, they usually the trusted ones. Also don't forget, credit card companies like mastercard, visa also offer "protection" and call any transactions into disrepute. Paypal also has a system, but I hear its like 60 days before they will do anything. Cavet emptor, I haven't have any problem when I'm using ebay. It depends what you want, beaumont tiles near bella vista was pretty good if you want an "up market" tile place. That is the place my builder use for tiles. When you have the time on the weekend pop over to ropes, pm me for the address if you want.
