I have WHAT in my yard? :
I hope your little chickie comes out OK! Rough start!
But remember, sometimes the hens seem to know if there is something wrong with a developing chick and they kick them to the side..... My hen picked up a newborn chick and threw it out of the box! I was so...
Yes, you can put some tape over the crack...how far out from lock down is it?
If there was not much bleeding then the baby chick may still have a chance......But seriously...until the bator is ready, stick the egg IN YOUR BRA...body heat does wonders for the little ones
