I have 2 newish Australorps. They have a coop like the "Dutch coop" on the photos page. It has a little enclosed area with 2 nesting boxes and a little space where we have put a roost. It has a ramp up to this section with a little doorway. Then they have an area about twice that size which is caged in. They also have a much bigger run area for during the day. We normally put them in the little house area at night with the door closed. Getting them in there involves a little bit of chasing around trying to catch them. My 7 year old son is very good at this. So to my question. We are going away for 4 days at christmas and have a friend coming by to look after them. Can we leave the door to the house open at night and just leave it up to them if they want to go in? We can put something across the run so they are contained in the little coop area. I think the whole thing is safe and secure and don't think anything could get in to them. We live in a suburban area with a few cats around. That was a bit long winded thanks for reading if you got this far!
