I have about 40 chickens ranging in age from 3 to young pullets. It seems like I always get about 12 -14 eggs. Mostly white as I have 14 leghorns. I need advice on how to manage my flock. I feel like I am always feeding way more chickens than what I am getting eggs. For those who cull according to egg production, how do you keep your flock rotated? Is there a certain age that you cull? A certain time you get more chicks? Currently I have leghorns, RIR, Ameracauna, EE, orpingtons, black copper marans and a mutt. Subtracting pullets and roosters I have about 35 hens, how many eggs are reasonable to expect during summer?
