I had two of my homing pigeons mate and lay eggs, one of them hatched. The one that hatched has feathers sticking up on the back of his head like a fancy pigeon! Take a look: Isn't that weird?

Is it unusual for a hen to late eggs an not have a mate an the eggs are actually fertile? I have a hen I had her several months so I didnt buy it with her being pregnant so thats not an option. I had birds laying eggs an notched she was sitting on eggs when cocks were sitting shes the only one...
