I have a toulouse goose and at least two other toulouse/roman females from last year's hatch. The gander is an Emden - unrelated to the mixed girls. I think they are getting ready to lay. Last year I only had the one toulouse so this wasn't anything I needed to worry about - but do I need nest boxes for them now that I have more than one laying female? Or will they just choose their own spot? I lock them up at nite but they free range during the day. They have a 8x10 indoor enclosure that is all open but I could divide it up if necessary. Thanks!
