Hi! I am very new to the chicken world...having had my first four (now three) for only two weeks. Since we got the first two from some friends we have had nothing but problems with them. They are/were about 1 1/2 to 2 yrs. old - still laying. One (a black sexlink) was pecking horribly at the other (a buff orpington). Most of the buff's feathers were gone - she looks like a turken I also got two more - 1 red sexlink and 1 maran who are much younger - hatched last May, so they are about to start laying soon. Anyway, the black chicken was being a bully so we didn't integrate them right away. Finally, the other day she started eating my Buff's eggs - naughty!!! So, we decided she had to go. Last night we did her in (she's now in the fridge). It was a quiet affair and it was very quick. We tried not to disrupt the others at all and it was about bedtime so I don't think anyone noticed. Anyway, right before we went to bed, we slipped the two younger ones in with the older one. This morning we woke up and everyone seemed fine - that is with the exception of poor old Rosie (the Buff). She seems very depressed all of a sudden. I went out to the coop to open the door and let them out, usually they are really excited to get out and roam around but she just stood there and didn't know what to do with herself. I went over and sprinkled some mealworms around for them to try to motivate them and get them excited but she just turned her nose up at them and went to stand on her perch. I also noticed that her breathing sounds labored and she has been sneezing/coughing all morning. I don't notice any mucus or swelling, comb is fine, no spots or anything else weird. She also laid an egg like normal. No wrinkles on it or anything (don't know if I should eat it though?). Now she is back in the nesting box just sitting there. It has been very hot here (up to 100 this week) so I opened up the door to the roost for some extra venthilation. Anyway, I don't know if I should be alrarmed or nervous? She hasn't taken a bite of food all morning or a drink that I have seen. One other note is that I found that she was very attatched to the other chicken (the one who is now gone). When we separated them poor Rosie had a heck of a time going up to roost alone - she would pace on the ladder and cluck for about 20 minutes before finally going up to roost. They were a very codependant pair. Any advice??
