I sat for a while with my three month old Rhode Island Reds today. I gave the friendliest one to a close friend of mine, who was absolutely in love, so I'm now down to 5. I'm almost certain that I have one cockerel and four pullets. The little cockerel is starting to get his shiny, pointy hackle and saddle feathers. None of the others are showing any similar signs, so I'm crossing my fingers and toes that my guess is correct. They've started their first molt, and I'm finding bunches of feathers in their pen.
We also hatched some Barred Rock and Silkie chicks over the past few days! Its so nice to hatch chicks again. Our incubator has been empty for the past few months.
Congrats!! So sweet of you to give away your friendly. Hen.
