Our Sebastopol gosling is four weeks old, and he has a thick layer of down, with feathers slowly coming in. He’s spending the day outside now, but we are still bringing him inside to his wire dog kennel every night (with some snuggle time in my hubby’s lap first). Our night time temps are going to be in the high 40’s/low 50’s this week. At what temps can he begin to sleep outside? He’s rapidly outgrowing the kennel!
