Ok so here is my story. About 3 years ago we got 4 chicks. We got the first two and then about 3 weeks later got 2 more and kept them separate until they were all put into our new coop together. They developed personalities and one of the younger ones turned into quite the bossy hen. Pecking at the weak, flying out and destroying our garden bed, and always first in line for treats. One of the original four was always weak and never laid. After a bought of pox we lost her for good and the rest have been living together for 2 years since. Now we are thinking about introducing 2 new babies into the flock as a transition as our original hens are getting older. Our coop has plenty of room for 2 more but we would like to stick to 5 total. But, after reading the horrors of introducing new chicken into flocks we are a little scared. Our barred rock is evil and ruthless but also the best layer so we keep her around. But we are worried she might take it upon herself to take out any new coop mates. We have a small urban yard so keeping them separate is not really an option. Though we would keep them in our brooding box until they become pullet sized and the weather warms up a bit. Not that big of a concern for the weather in SoCal. On a separate matter, if we do go for it, our local feed store has some chicks. We were thinking of getting an americana for those beautiful eggs and then either a maran, a frizzle cochin, or a rhode island red. They have the later 3 right now but wont get in any americanas till next week. Would it be ok to get one now and another a week later? We heard its best to raise new chicks at least with one companion but we worry if we don't get one of the breeds they have now, by the time the americanas come in there will be none left. Its a silly worry but we would really like those particular breeds. Will a week alone be traumatizing? Please give us your thoughts! What should we do?
