Yes, I will put the mirror back in. A friend at work told me that if I put new chicks in with her, she will kill them. She is 2 1/2 weeks old and about the size of a small robin or dove. What you all think? The local feed store was closed today, so I was not able to get any chicks, but I do have an order of partridge cochins shipping the week of the 19th, and an order of Black Jersey Giants shipping ASAP, hopefully early in this week. Will I have to keep them separate until the newer chicks get some size?
She will likely be fine with new chicks, but you will want to watch them at first to make sure. Adding multiple birds is always easier than adding just one.
