I have Rabbit cages Not in use but the wire is 1x1/2 inches Im thinking they can slip there little legs out . So im thinking of making some Grass mats for them and my chicken coop run. for winter time when they do not get to run the yard . is there some Ideas on grasses or even maybe something that they can also eat. the cages are 9x3x3 2 holes of 3 ft each and i think this could be a fun to do any Ideas on what i could start with ? I was thinking rye or wheat but ?
