Not sure which is doing it.... but I strongly suspect Samson, so each morning I hear this incessant knocking on the door to the pen. They want OUT and they want out NOW! Samson only crows about every 3rd morning... but somebody is pecking away at the door EVERY morning. Since they are right outside my bedroom wall I hear it clearly. They do it really loudly and won't stop! Is this normal or should I put some Prozac in the water?
