I have some 10 week old chicks, and of course my husband got addicted and we ordered day old chicks that will be here next week. I have heard not to introduce all of them till the new ones are about 14 weeks old. Is this correct? Also does anyone have personal experience with the night time introduction?? I know I have sometime to think about how it is going to happen, I just want to make it less stressful for the chicks. I had a neighbor growing up that had chicks and she just always kept them separate for a week by chicken wire in the run and then just let them go on into the flock at daytime. I am going to do something similar to that during the day time and then keep them separate at night, but when actually letting them be apart of the flock should I just let them go like she did or should I do the night time method? Thanks! I know this question has probably been asked 10439749 times. I apologize. Any advice will help.
