So we have been at this chicken keeping thing for a couple weeks now. So all birds are still very new to the area and each other. The two black austrolorps, a buff orp and prod red are all doing great. Laying eggs and sleeping all together and acting as chickens should. My brown leghorn is not acting well. She sleeps alone in the nest box, she acts really sleepy all the time, she is not laying(we bought her knowing she wasn't yet), she is being picked on a little by the big production red. She gets run off the food first thing in the morning. However I do see her get to eat and drink. She just has to do it last. She sits by herself out side in the run as well looking very sleepy and lethargic(eyes closed half the time). I can't tell if this is normal molting behavior(pretty sure she's molting) or if she is sick or if this is just a bird that did not handle the change of a new environment then two new birds being introduced a week later one of which is picking on her. I'm seriously considering putting her down. She just doesn't seem like she's having very much fun with life at all and I just don't want her to suffer. If this is normal for a stressed or molting bird please let me know. I don't want to put a bird down needlessly buy also letting them suffer isn't good either. Thanks.
