Hi all. I just got 2 RIR and 2 Ameracauna chicks that are 4 days old. They are in a brooder with a red heat light. However, 1 is extremely noisy. She is being quite noisy only when we put them to bed. Is this normal? They are all eating drinking and pooping fine but last night only 1 of our girls was noisy and tonight she has encouraged all of them to click as loud as possible. Are they just being annoying to tell us that they are mad and want attention or could something be wrong? They are not cold because they are wandering around and playful and they don't seem hot because they are not avoiding the hot side or panting. Any suggestions?
