Hi, one of my polish hens hatched her first couple chicks yesterday & I noticed her comb is so so pale. She's been good about getting out to run around, eat & poop for a little bit every day but she just looks worn out. She is also doing a low gravel-y sounding growl when someone gets too close which is different than the hollering she did early on if we got too close to the next. Is that normal or could she possibly be unwell? Thanks in advance, these were are first "au naturale" chicks so we are totally new to this part of the process. I have to say, what a miracle!
