Correct and they may be carriers of something that you should NOT bring with you to a fair.Yes, we've been washing and changing in between each coop. We are trying to put the new barred plymouth rocks in with my original flock this week, and then we have a smaller coop specifically for my bantams I'm gonna do for fair. We have these chicks inside, but bring them out in a pen to get some grass and sun and exercise.
I thought about how they might be carriers, but I didn't think about if it would go away or not. Would that just mean they could never go in with any of my chickens safely?
I highly recommend keeping a closed flock until you are able to have some testing done so you know what you are dealing with.
What state are you in?
Every state has a state lab that can help you with testing.
