Please help! It's 20 degrees out and my hen is acting sick. I brought her inside and she is making gargeling noises everytime she breaths and is now acting like she is going to caugh up flem. I am haveing computer difficulty so I have to make this quick. I did change their bedding from straw to pine shavings not a couple days ago. Is this a respretory illness? I'm going to remove the pine shavings now. Edited for this; she is eating scratch and scrambled eggs now, haven't seen her drink water yet.......I'll make her a mash with layer pellets soon. Thanks!!!!
