our pullet did that too a few days ago when she laid her first egg! She started cackling loudly before and after she laid the egg! 
		
		
	
	
		
	 I didn't know why but now that I see all these other people with the same problem, I am guessing it's just natural. LOL 
		
	 it was like she was telling the others, "Hey! Look at this! an egg!" 
		
	 so porud of her.
