I bought 4 young chicks (3 RR Red and 1 barred rock) and they all get along well. They are outside in a 3 x 3' coop at night and a 4x8' run in the day. I move the run daily. They are about 4 1/2 weeks old now (just getting feathers on their heads). I fell in love with 3 tiny easter eggers a week ago and they are in my cardboard box brooder with a lamp, in the bath tub. I plan to have them all together as soon as possible, but am worried that the little ones will get killed by the bigger ones. The little ones can't go out full time for a couple of weeks, though I take them out in the sun when it's warm enough now. I'm in southern Oregon and it's been 60 to 80 degrees in the day time and the coop is heated at night. All pullets (as far as we know). So, will a 3 to 4 week difference in age be a big problem? Is there a good way to introduce them? Am I an idiot for taking the easter eggers?
