One of my chicks hatched some time last night. He seems happy but his feet are curled up and he can't walk or stand. He is a late hatch and the hen has not yet taken him outside. He is slightly inbred as his mother is half sister to his father. Could it be that he is still weak from hatching? Does his mum have to show him how to do it? Is there something wrong with him because he's inbred? Please help, he is the only one to hatch and both me and the hen would be heart broken if he died.
