Are the rotisserie chickens ready to buy when they open at 10?

Yes they are

I think tgey are around 11 ish

No they aren't usually ready until just before noon, but sometimes you can get them cold from the night before. Those are usually used for the homemade chicken salad and the potpies.

I thinkk I have seen them when I have been there at opening.

I believe they are, we picked one up before 11 one time for an event. They must have some cooking overnight or someone gets there real early to get those delicious birds cooking.
