Hi, this is my first time hatching under a broody hen. This morning we went to go check up on the mama to find two newly hatched chicks sprawled in front of her and not under her. They were cold to the touch but were alive. She has two more chicks under her who seem healthy and super fluffy. I jave taken the two into my incubatorthey are moving a little but no chirping is this normal chicken behaviour? Did i disrupt natures course?
