Building An Outdoor Rabbit Cage Rabbit Hutch Problems?

Rabbit Hutch Problems? - building an outdoor rabbit cage

I am building a hutch outside, outside, through the conversion of an old bird cage. I have a small problem with the ramps. As can be steep? In addition, the width of the ramps is not? My rabbit is larger, the size of California, and weighs about 1 pound and a half. I suppose you can take your size. I might add, begins the end of the ramp so that he can maintain his control when climbing. Thank you!
