Flying Reindeer
This was a prize on the Christmas 2011 Event.
Once placed on your farm, the "reindeer house",
the reindeer will hatch from a purple Christmas Ball:
The incubation time is 168 hours.
Which can be reduced to 1 hour if you add an Egg Warmer (39 BB in Supply Store), see above post#1.
Once ready to "hatch":
Each time it's "ready":
you'll get a 450 EP hatching bonus,
and the reindeer effects are:
one star
with a cool-down timer set to 7 days.
You can have a maximum of one item per field.
