The other day, my EE laid and came out singing. The roo heard it and made an absolute beeline for her, trying to "do her" immediately. (She doesn't like him very much.) Hmmmm.
I have to agree with Featherbaby and Illia. When my ladies lay, Sarg will almost kill himself charging in to "ave a go". Hen see's him, assumes the position, and........PRESTO! Another egg about 5hrs later. If you watch you may see this too. But the preditory study is infact solid.
"I laid an EGG!! An EGG, I tell you!! Look! Do you see that?? I did that! I am part of the ONLY animal group that can do THAT!! AM I AWESOME OR WHAT??"
