I feel horrible--I have this one chick (about 12 weeks old) who is much smaller than the others who are the same age but different breeds. My little chick is nicknamed Penguin. The other day I was shutting the door to the coop, and it was kind dark out. I shut and latched the bottom door (top half of the door opens separately) and I looked in and saw that Penguin Chick wasn't moving and was just standing pressed up against the door. I flung the door open quickly and found that I had closed her tail feathers in the door!!! The poor little thing didn't make a sound, it's a good thing I double checked inside the coop or she would have been stuck there all night. I felt so so bad. To make it worse, in the past few days all of her tail feathers that got closed in the door have broken off. Now she just has feather stubs and she looks even more pathetic than she already did. My poor little chick! I know she's going to be fine, she doesn't act harmed and it just clipped the feathers off, but I still feel terrible. Do you think they'll grow back anytime soon? Or will I have to wait until she molts for the broken feathers to fall out and fresh ones to grow back in?
