I have a 6-week-old chinese weeder gosling. He is not yet fully feathered down his back. We are reaching night time temps around 50 degrees. Does anyone know if he needs heat at night at this stage? I have been bringing him into my greenhouse at night (in a large cat kennel) but he makes a royal mess! I would love to leave him outside all night (he has a small doghouse he could shelter in) but I am worried that 50 degrees is still too cold until he is fully feathered.
