Chicken math. I just foolishly bought 4 Easter Eggers. And the guy threw in a barred rock for free because we mentioned we hoped we had a rooster in our bunch of 19 chicks .... None of which are showing any signs of being cockerels. We need to build a greenhouse off the chicken porch for winter or we will absolutely not have enough room. The coop is 9x11 and the south facing porch, which because of the way the sun hits it stays as warm as or warmer than the coop during the day, is 8x10. We could construct a greenhouse type seasonal structure off the porch as big as 10x16. We will have around 30 chickens....just depends on if anyone is a cockerel and how they do this summer with predators (lost 2 last summer). And all the other things that chickens face. What have I done?
