Hi, so we just had a shipment of 4 chicks come in, and decided that we might want to add one or two from a feed store- however the feed store chicks are about a week old according to the store, and ours are only 2 or 3 days old Would it be a problem combining four day old chicks with one or two week old chicks?
You shouldn't have any problems. But there may be a "ritual" peck on the head when the homies first meet the new comers. That should be the extent of it. They should all get along just fine.
