Just checked on our 3 chicks. They are almost fully feathered at 24 days of age. Sadly my last look to avoid frightening them into fledging too soon. There are 2 females & a male. Both adults were screaming their displeasure at my intrusion.
I was just watching the mom trying to feed the chicks. They were grabbing the food from her and fighting over it: Tug of war big time. She had to grab it back in order to tear off small enough pieces that they could swallow.
