I am thinking of getting some bantams this year for the very first time. But, I do have some questions!! In general, how many bantams will equal a buff orpington in space? For instance, if I have 4 buff orpingtons than how many bantams could I get to equal the space they took up if I placed the buff orpingtons? Also, I am looking at these breeds: silkies, buff brahma, barred plymouth rock, easter egger, wyandotte, and frizzled cochin. Out of these breeds what would be your top two breeds for: 1) Not flying out of the run as my chicken fence is only 4' high 2) Being hardy in winter/northeast without needing to be pampered 3) Laying a minimum of 2 eggs a week (egg laying is important and we need at least 6 eggs a week total from our flock-how many bantams would I need to get this number) 4) Being able to raise a batch of chicks 5) Being good free range foragers as I have a large grass run 6) Being gentle with kids Thank you in advance for any advice or opinions!!!
