My daughter noticed that her 6 day old silver laced cochin chick is opening and closing her mouth almost constantly for the past couple of hours. She is drinking and did poop a little while ago but hasn't been seen eating. She is chirping but is sitting in the corner of the brooder. She has been fine up to this point. What is going on with her and what can be done to help her so she'll stop? I thought that maybe she is over-heated..... Any help would be great!
