Last week, my 8 month old brahma let out a sneeze and she has been making funny noises. Now, the last couple of days she is coughing more frequently and last nite she sneezed on my hand and mucous was present. Her eyes are bright and alert and her poop is normal. She seems to be acting fine, but she was very vocal the other day when she layed an egg. Also, a few weeks back, I found an egg broken on the floor of the coop. It had a very, very thin shell and I think it broke on the way out. I am sure it was hers. I wasn't too alarmed as I read that happens sometimes. I really don't think it would have anything to do with her symptoms now, but thought I would mention it just in case. I was going to go get antibiotic to put in H2O today. Would that be okay? Or should I do something else? Maybe bring her inside the rest of the winter? Or do you think she'll be okay to stay outside in these freezing temps? My flock is eating Purina Layena pellets. I use large pine shavings and I just swept out the coop and replaced shavings a week ago. I clean poop every other day... Also, I should mention....when the nighttime temps get in the single digits, I turn a red heat lamp on. Bad idea?
