And if you expect a cracked egg to "hatch" forget it.
Air got inside of it and now the baby bird is dead.
Toss it away, it is no good.
So on thursday my cat brought home a bird egg and it was cracked i thought where he had put his teeth into it so i thought it was dead but then i candelled it an could see the veins and everyday the veins have been growing so does that mean its hatching soon? I have it in a warm and safe place btw
