letting out

The gosling that hatched back here , has been looked after by its hen amd has continued to grow - and its now bigger than the hen.

So its time it went out into the big wide world.
We already have a couple of geese , who have a gosling.

So they need to get acquainted. If we just let the gosling out , it may get chased away  , or run away , form the existing 3-some. So the solution is to make a pen and allow them to get acquainted but leaving enough space for the new one to avoid the older geese if necessarily.

 And we think the new gosling is male, so he has (provisionally) been named 'Christmas'.
