Right now we have 6 chickens (2 roos and 4 pullets) the 2 roos will be LEAVING soon, so that will just leave the girls, Thank GOD! Any way, they are approx. 27 weeks old and we started them on scratch a few weeks ago when it got really cold. They have their crumble layer as well and my son tries to gather as much green grass as he can (they are NOT freerange). So I am wondering if they are getting enough scratch or too much. I don't give them any scratch on the warmer days except in the early AM when it is still cold. How much scratch should 4 pullets get per day when it is cold out?? Also what else to feed them during the winter when all the green grass is no longer there???
