I will be getting chicks in about a month. I have found a selective breeder (Claborn farms) with very healthy flock that I will be driving 4 hrs to pick up 10 day olds, standard-size from them. They do not have bantams which I'm planning to order 5 by mail from another source. AND I really wanted some colored eggs in my basket so I'm thinking of getting some EE's or Americaunas from a local breeder. Probably only 5. So a total of 15 full-size and 5 bantams. Is this a good idea? Should I isolate them into separate pens that are close to each other or can I let them intermingle since they will be straight out of incubator? Or at least only 2-3 days old. Should I be concerned about disease since coming from several locations? Yes, it will be tricky to get all of this timing down but planning to get the out-of-towners first, then locals, with the mail order bantams arriving soon after. I could wait till spring for the bantams and EE's but I'm impatient!! and if I have to do all the work of feeding and letting in and out all winter why not get enough for all the eggs and chickens I want to have in the first place? I'm planning to keep all of them in my newly built 9x12 coop with a Mama Heating Pad...I will have two of the MHP's ... for warm ups. Since it will be July, high humidity and 90's temps here in NE Texas I'm thinking they will be okay to start immediately inside the coop. I will keep a very close eye on them the first few days to be sure they are eating/drinking well. Also planning to feed fermented feed and immune boosting water from the start. I hope this make sense!!! Sorry, it is such a lengthy post! I am truly thankful for all of your advice! I'm learning SO MUCH on this site! Totally dependent on y'all for coop design ideas and brooding info.
