Trying out a new baby holding / grow area.. They seem to like it. They can mow down a lot to Timothy hay for such little things.. Many things I worried about using a 56 inch Pet play pen. The barn gets really warm this time of the year for most of the day my main concern that the play pen might be too airy was unfounded, actually makes it more comfortable for them. Always love getting assortment just for the fun to see what colors you get lol.. always cute little things and having a blast..
