I have a flock of 40 chickens ranging from 2 months to 7 months they are in 2 coops 14 x 7 with runs totaling about 300 sq feet. All have been healthy and active but the last 2 day we have noticed the only pullet laying is making a barking sound and a 3 month old pullet is doing the same. There drops look fine and there is no other changes in there behavior. The layer did get very wet a few days ago from a rain storm, Is this something to be concerned with?
