Hi guys, i have a small flock of 5 chickies...( three leghorns, a buff orpington & a RIR) and i really want them to lay eggs with dark yolks. Like the ones when you are watching a cooking show from the UK..they are super dark orange. Please help. I know that from other threads that I should stick with formulated feed, which im fine with, but would love some tips on additives to their diet so their yolks get that super rich look. They do get 'free' time most days..in our back yard & garden, but I have to balance that with the dog...who unfortunatly would love to get his mouth on one, so they take turns.
