I think my four chicks are ready to take their first trip outside (they're a little over 3 weeks old and it's been nice and sunny). I was going to build a tractor for them but I googled for ideas and only came up with full-out mobile coop designs. I think all I need for now is a wire enclosure that will keep them contained to a smallish area. What I can't figure out is how to get them in and out of it without them escaping all over the yard. If there are plans posted somewhere or any tips you can offer, I'd love the girls to have an outing this weekend but I don't want to be chasing them all over the yard!
