Hi everyone. I am a new chicken owner (first flock last year) and I am having trouble introducing my new chicks into the existing flock. I have 9 existing hens and 9, 15 week old chicks. Last week I put the new chicks into the main coop/run and that is when the problems started. The older hens will not let the new chicks out into the yard, run them away from the feed/waters and afre just being mean in general. I have lost 2 of the young ckickens in the last 3 days and I think it is because they were being kept from food/water. I have since sectioned them off with supplies of there own. Ideas gladly excepted.
