The boys seem pretty good with the grass I gave them today, I guess I will feed them a mixture of grass and hay. The boys go through 2 bags of hay a week, we usually get that bagged Kaytee hay, I can only find it in the 24 oz bags, I live in a small town so there isn't many choices. The boys are also still growing so they will probably be eating more as they grow.
I have an acre and a half property so I can probably set up a nice area for growing some grass for them. We have a small area behind the shed where we had fenced in where I use to use for the dogs. Do you think the dogs using that area for a potty about a year ago will make a difference? The grass in the fence is getting a bit high, I was going to take down the fence and mow it but if I can I might use that for the rabbits instead. I would love to be able to let the rabbits outside in the fence for like an hour or so in the morning, but we have a lot of hawks around here (even though I doubt they could lift up a fully grown Flemish giant), and I also don't want them digging out.
