I find it quite strange that they have to give birth to themselves. After hours of pecking and squirming, they finally free themselves in exhaustion. They are left in the incubator until their feathers are all fluffy and dry.
They are then placed into this temporary home where they will stay until the weather is warmer and they are big enough to be introduced to the rest of the flock.
They are so cute! It took all of my willpower not to sneak a few into my pockets to bring home. A few of these will join us eventually, once they are old enough.
