Whooo - hooo ----> good luck with your hatch(es)!!thanks to both of you for your info.
My avatar is a Gold Cuckoo Marans Roo. He is lovely!
I have heard the same, about later laying pullets. Makes since, as it should be a more mature bird, at point of laying.
I have my 1st four Cream Legbars in the incubator now. The trio live at my Biz Partners house and this is our test hatch. She has 4 under a hen too.
