I've never had fertilized eggs for one of my girls to set on but my Izzabelle used to take her job of watching over our first 6 day old chicks "very" seriously. This is an old pic but it always makes me smile.
They are. Have all but Sweetpea (RIR) from that group. Those were my first chicks. Actually, only ones I've had as chicks. They were just hatched when I got them. Izzabelle just adored them. She'd spend hours with them. They'll be 3 this May. Izzabelle & I would sit in the grass together and watch the chicks play. It was the most peaceful of times.
