One of my eggs went broody, i kept removing the eggs thinking it was a phantom pregnancy but she sat on about 3 for like 2 days and those yolks are the ones that look odd, with a large mass of difference. on all my eggs (i done about 10) they have a bullseye like shape. Now the odd thing is, I have 3 10 month old hens? no rooster? at least i didn't hink i had, do i have a transgender chicken haha?!?!? !
