Thanks! I had one a while back with unabsorbed yolk but it looked different than that and it was weaker. Hopefully this one will do better than the last one.
I hatched out a d'Uccle chick that has a weird round thing attached to its bottom. I don't know what it is and the chick seems to be acting fine. He/she is still in the incubator because I'm afraid that if I put it in the brooder the other chicks will try to peck at it. This hatch didn't do so...
