Awwwwwwww! Those are great photos of the other ladies checking 'em out. And they're just adorable!
My Buffy has been bringing the GrandChick out every day for the past 5 days. She chitters and puffs up a little bit if the younger chickens come near, but there have been only one or two "Stay Away!" shrieks when somebody got too close. I wonder if she gets dizzy, because she keeps turning to keep track of the chick and/or anybody else around her. She looks like a toy on a spindle, almost; swivel on spot to the left, swirl almost all the way 'round to the right, take a step, turn back, call the chick, turn forward, take a step, turn back, swivel right... etc.
Her comb and wattles are starting to pink up again; I noticed how pale they were at time of hatch.
(Just thought I'd share what my Buffy was doing, because she's a couple weeks ahead of yours.) Please continue to share pictures!
