I've been reading and searching a lot, but can't seem to find an exact answer that I need. Basically, my problem is that with the 14 chickens I have, I'm only getting 6 eggs a day. I don't mind having a few old hens, but if that many aren't laying eggs, I don't want to be feeding that many. The ideas that I've liked so far is separating them into a cage for 3 or 4 days to see if they are laying eggs or not, then tagging their legs with certain colors to tell which ones are layers. I've got some ideas but wanted to see if anyone else had dealt with this before, and if they had any pictures to show for it, because those help me the best. I can't post a picture to show my coop, since i'm new. I will see what I can do later. But I have one corner of my coop that I could possibly build two shelves in out of wood and make a front wire door. My question, about how big does it need to be, if I'm going to keep a full grown chicken in it for about 3 days?
