Cage building questions

[Andrei]

We have Bermuda grass in the yard. Couldn't I just use that for the rabbits? Is it all right to give them freshly cut grass?

Yes.
Today a hand.
Tomorrow a hand and a half.
If you give them all at once they will gorge and it would be OK if they eat that all the time.
If it is the fist time ....... just like a kid in a candy store.
