hi is there anyone who can help !! we have been incubating hen eggs ,one hatched today ,it was 3 days overdue ,it piped at noon and hatched at 6.40 there seems to be something attached to its rear end still ,i thought chicks should hatch and be clean ! we are new to this and finding it very stressful !!! also what is the kindest way to dispatch a chick,(not a nice thought ) if it has to be done ,any advice would be great ,thanks
