I'm watching them closely. Wilma and Betty were panting yesterday too, all the other birds are used to it. Betty went into the coop and stayed there for a while. The coop gets way too hot to stay in. I had to get her out and close the coop for a couple of hours. It seems like Betty was in the lower pecking order in your flock by the way she's acting, just like Amanda, but the 3 girls are becoming closer to each other and Amanda isn't running away like before. I'm not getting any eggs from anyone right now so I doubt I'll be hatching anytime soon.
