if you are giving them no gmo chicks starter that will enough .don t over load them with egg yolk .20% protein is enough for them .
chooks man
1 egg yolk for 5 chicks and a broody and 2 egg yolks for 11 chicks and a broody. I think it is not too much. the guy at the feed store told me it is written there is 21% protein but there is 18-19% only. at least he was honest.
I give them dandelion leaves as well. I am worried they might get worms as it was rainy for a while and the broody was scratching and fed them a lot of earthworms. the other broody with 5 girls is in a sofa bed brooder so they are safe at the moment.
