I'm convinced!!! I was just hoping to get them together while the first batch is still pretty young. I'm kind of a "just rip the bandaid off" kind of girl. I don't like prolonging things. If something bad is going to happen, I'd rather get it over and done with. But, you are all right. It is not worth the risk of infecting my little ones. Thanks.
Now, I have to figure out some kind of shelter for the 2 EEs while they are quarantined. I have enough room to give them a separate part of the run so that they can all at least see and get used to each other. But, I don't think I can partition off the coop into 2 separate areas. I will have to have a small temporary coop inside the run. At least I have 19 days to work on it! But, who's counting?
