Got a question for the chicken peoples..... I have 2 Bantam Cochin hens, 2 Silkie hens and about 18 Serama hens, my question is will my 10 x 20 be big enough for all of the girls and will they all get along? Don't want any problems, wasn't sure if the Cochins or Silkies would hurt the smaller Seramas. I have some smaller cages that my husband built and I plan on using those for the guys. How much space does a Bantam Cochin and Silkie Roo need? Thanks for any advice you can give. We are scheduled to have our first frost and possible freeze tonight so I am trying to get everyone ready for the winter.
