My neighbor, the gardening guru, used wire fence (2"x4", 4 foot medium weight fencing) hoop/cages around her tomato plants for supports this year, rather than stakes or the commercial tomato cages which are pretty flimsy, and that worked out beautifully - especially here where we get some pretty high winds that will take a staked or otherwise supported plant right down. The additional advantage to this is that it was pretty good protection from chickens - though they could get their heads thru and access a little of it, they couldn't reach most of the tomatoes and couldn't do much damage. I'm going to try that next year. I have trees and shrubs in the chicken run protected just by little 3' chicken wire hoops flimsily supported with stakes, and that has served very well to prevent chicken damage while the plants are young, so that would also work if you didn't have too many plants. But I generally don't let the chickens into the garden until everything is pretty well harvested.
