Chick report:
The little one with the unabsorbed yolk sac had it drop off in the night.
He has been living in the house but I put him under Gracie Belle the wonder broody tonight. She has 5 -3 day olds from the NYD HAL and the little guy I am grafting to her is 8 days. I think she will accept him as she has co brooded before and willingly sits on any and all chicks who have sought her out regardless of who had hatched them. I slid him under her after dark and she did a little adjusting but seemed unconcerned.
If you want to read a bit more about this little chick and see a pic you can check him out on my daughter's blog

@PetRock I googled images of Langshan chicks and this little one sure favors that side of the family. I of course have no idea if it is a cockerel or a pullet but could see the Langshan in it from the get go. It stands tall, is HUGE and the coloring and markings reminded me of pics you had posted last spring. Hoping the pullets stand tall too but am fully prepared for this to be a cockerel. The whole family is quite smitten but I do hope the mama takes to him.
