Today I found out that my three 7 week old mutt EE/RIR babies are all Roos. My 9 week old ones are hens. So my roos have a new home this weekend. I wanted more layers though. I located two wyandot silver laced bantams close to me that are hens and are about five months old. Please tell me if they will fit ok with my 9 week old ones?? THEN to my dismay, my silkie chicks that were due tomorrow from Cackle hatchery, did not hatch. THe heat caused a problem there. So they rescheduled me until August 12, which is really pushing it for me to get some in with my others. How do you mix chickens??? I am wondering if I should cancel the order now, but I REALLY WANTED SILKIES!! I probably won't as I have considered keeping a couple inside. I don't have alot of land for alot of coops here and my chickens can't free range. I am a city lady. I wanted a flock of maybe six to eight bantams. Of course I am keeping my two Mutt hens too. So I am ready for all you experienced people to give me advice on all this. Thanks. OH AND ALL THE INFO ON WYANDOT BANTAMS THAT YOU HAVE PLEASE. HOW MUCH DO THEY WEIGH? ARE THEY GOOD NATURED?
