Hello! Today my family's chicks arrived in the mail. When we took them home and released them into the brooder, we noticed that one of our Mille Fleur D'uccle bantams was particularly small (maybe half to 3 quarters the size of the others). I kept an eye on him/her, and also noticed that she stumbles a bit when she walks. It's not like she faceplants with every step, she just stumbles and every occasional trips into another chick or the wall. Is this normal? If it's not, how can I help him/her? Thank you so much for your help!
