Drunk acting chicken.

[kmearle26]

I have an almost 3 month barred rock pullet and columbian rock x. When I let them out in my yard they have a spot they like to dig at and lay down and have dirt Baths. My question is 2 times that they've done this when I go to get them to put them back in their coop they don't move. And when I put them back into their coop they flop over and act like they can't stand for about 5 minutes, tails drooping and just cant seem to get their balance. After they are fine, eating, drinking and running around. I haven't had chickens in years but don't remember them ever doing this. Should I be worries?

Sorry no one has replied yet! My first thought would be what did they eat or get into. But unsure that if they perk back up quickly if it's that but just a thought.
