I have been hanging out here in the wings reading about all I can on chickens for several mounths now and about 2 months ago I took the plung and started a small flock. I have 3 BR hens and 1 RIR rooster all around 5-7 months of age. I did not get them as chicks, I actually got them from some one that started to raise chickens then changed thier mind. The hens have been laying 2-3 eggs a day and that is plenty for my family. They get all the of water and 16% layer and scratch feed plus other goodies that they can eat. There bedding is pine shavings. My problem is with just one of the hens. Over the weekend I noticed her comb was getting a dull brownish red color and she started to make a gurgle type of noise. She does have the runs but she is eating and I belive drinking. I belive that she has stopped laying. She acts fine except for the gurgling noise. Some times she opens her mouth and does the gurgle. I have no idea what it could be. I treated them for lice and mites when I got them. The other birds seem fine and are still laying eggs. Any ideas would be great. Thank you.
