We need to alter our chicken house gate to allow chickens to pass through but not wild birds. Answered
We have covered the whole structure with bird-netting to keep wild birds out of the chickens' food, with some of it draped over the gate opening to within about 30cm of the ground. We need to be able to get in and out of the full-height gate easily ourselves, as well as allowing the chickens to go in and out freely. The trick is how to do that without allowing wild birds to also pass through.
I thought of leaving the netting draped over most of the open gateway (we shut the inwards opening door only at night time) and then having a smaller gate at the bottom that the chickens can push through at the bottom 30cm, perhaps made of a cafe-blind cut into strips and fixed to a rod attached across the lower part of the gate.
Alternatively, we could cut out some of the lowest horizontal bars of the gate and replace them with a lockable flap, hinged at the top. Any ideas of what the flap could be made of that the chickens would be able to freely pass through and wouldn't be frightened of? I made a doggy door in another gate out of the lid of a plastic storage container but the chickens don't go through this (and I don't want them to learn how).
I would appreciate any suggestions.
