We intervened in a natural hatching last night where for almost 24 hrs the chick hadn't made any progress as far as breaking free. Anyways, chick was helped out except the latter half of it so he could 'do it' by himself. At 9pm last night the shell was still attached by a small fiber (umbilical cord like) but he would just pull it around. Now it's 7 am and it's still there a little dried up but there. Do I let the egg just follow him around or snip it off?? Nervous to cut that lifeline if it's a bleeding line!! Never have had to do this kind of thing before.
