We are getting ready to endeavor on a huge poultry yard, with multiple pens and runs. We have over 50 chickens and adding more as they come out of the incubator. We will have about 40 egg layers of mixed breeds (no roos with them!) and we have 6 different breeds of show/breeding chickens, ranging from small Dutch Bantams, up to the biggest Buff Orpingtons I have ever seen. So my questions are as follows: How big of a run do I need for the egg layer pen? I have a shed we are converting into the coop that is 6x8 8 ft. tall. Do I need more space than that for 30-40 egg layers (for nests and egg boxes). How big of a run should I make? (*Is it ok to have this many birds in a group or do I need to knock it down to two or three pens of 15?) How big of a run do I need for 3-5 bantam show birds? I have the columbian rock bantams that I have kept in trios and most likely won't ever put together in the same pen (we had the roosters fight to the near death, it was horrible). I will also have a pen of 5 Dutch, a pen of 5 RIR Bantams, 5 Golden Polish, a pen of bantam cochins and two pens of Silkies. I was thinking of doing a small 2x3 hutch/egg box with a 3x6 run for the bantams and a 3x4 hutch with a 4x8 run for the full sized/larger bantams. I also have full sized Buff Orpingtons and Silver Laced Wyandottes which I feel need more space than 4x8 what do you think? I will have 3-10 of each of these varieties. Thanks everyone for your help, you're all so.....Helpful!
