I'm due to go on holiday next week and have asked the neighbour to look after my hens but don't really trust them to do so (they thought we was going away this week as well and never turned up). My hens are use to being free range and always have been, so really don't want to build a run for them and also worried the fox would get in the run and house at night. I've read somewhere you can get an automatic door/ side hatch. I was just wondering if anyone has ever built there own or knows a good website to do so?
