I have a one year old Plymouth-barr named Chicklet. She hasn't laid an egg in 3 days. She is eating, drinking and behaving normally except she is walking around w/her beak open. Do hens pant? I'm in south jersey and it has been 95*-97*degrees for the past 3 days. Is it just that shes hot or could it be something else? Thanks, shes my baby, I'm getting a bit nervous.
