I don't have Pekins. I have Welsh Harlequins and Golden 300's. In the past 2 weeks (after the Welsh Harlequins started laying) I have been getting extra eggs.
There has been 4 days in the past 2 weeks I got extra eggs. I am not sure who is laying them but I suspect it is one of my Welsh Harlequins. I have noticed
my ducks seem to go through oyster shell much faster than my chickens.
