I am looking for some advice on this. We have 2 bunnies we got in March or so. The male is very laid back and no trouble, female is a HUGE trouble maker. Both are fixed. This summer we built them a NIC cage outside and let them run around while we were out there. They both really loved it. They could eat grass, get sunshine, etc. Well my kids forgot to close the door one day and upon panicking we realized they were still in there. In fact, we left the door open a lot after that, closing it at night. They never strayed. Until they moved to the bushes. We have a large brush area in the back of our yard. They have been living there for about a month now. They come out and greet us when we are out. We make sure they have water and they are quite full on natures food. My husband even built them a permanent shelter out there for them to use. I know SHE is much happier outside. I see her out there binkying and just loving life. He seems happy also. Today my kids picked up the male and begged me to bring him back inside. I did. I just don't know what the right thing to do here is. I don't want to separate them. They are happy together, eating together, grooming each other in the yard. It is definitely much nicer without the female inside because she is just insane. Is it wrong to bring the male back inside now that he's had a taste of freedom? Plus I'm separating them. He seems to be doing just fine out there with her. We have an acre lot, with tons of wooded area behind us. Not fenced in. But they never leave this spot in our yard. Opinions? Also, I should mention I live in WI, so winters are harsh. But we have wild rabbits in our yard as well and they seem to do fine. A breeder told me he's been raising rabbits for 22 years here and they've all been outside. As long as they have shelter and hay they are fine.
