Good looking place.....Great to see a post from NZ....Actually 3 feet is not high for medium and light weight chickens(Chooks).....Wyandottes, Brahmas, Giants, Cornish X's, would be ok...But the hybrids you mentioned need a higher fence......I had a Buff Orpington from McMurray(Hatchery Type and smaller than heritage) that flew onto the barn roof and made a nest there ....Only noticed it when the eggs started to roll off.....Take Care......
Will I be able to keep chickens from jumping my fence? - Page 3

I read through a lot of the replies on here and they seem to miss the mark. The issue is not as much the height of the fence, but the type of fence. Chickens will go up and over even a 6 foot high fence if they can see the top of the fence. A 40 inch wire mesh fence with no top-rail will probably keep them fairly well contained, provided they have enough space, however if there is a top-rail or the fence is solid, they will eventually hop up on it and perch for a little bit, then hop down on the other side. If they can see through the fence but don't see a place to perch on top of it, they will just pace back and forth but will rarely if ever go over it.
mcmarsh is having that problem with his gate. If they can see something solid they will get up on it. From the picture he posted and what he said his 40-48" fence was working just fine other than the gate.
