Ugh...I think I'm going to be faced with this issue very soon, perhaps in a day or two. We're relatively new to owning chickens, purchasing our first in May of this year. We've had to cull before...we had two brown leghorns, both were purchased from a comfrey farmer, where the chickens were 100% free ranged, and ate, from what we were told, comfry day in and day out. I'm not sure if this did them damage, but we think it was either that, or something genetic, as they got sick at the same time, both with the same symptoms, and they were in a flock of other birds that never got sick. They went a "long" time before we finally put them out of their misery. They were not eating. Their faces were so puffed up they couldn't see directly in front of them, so foraging was out of the question, and they were losing weight rather quickly at that point. It was an easy decision to make. Now, however, we have what may be 2 more decisions to make. I've asked questions about their health here on the forums, but you can only get so much online. We are now faced with the possibility of putting down both a new laying hen, and our only mature roo, and frankly, we're pretty sick over it. So I guess we're wondering...how far do you let things go before you cull? How long do you give a chicken to work it's way through being sick, compared to ensuring a chicken does not have to endure more discomfort that it should? The chickens in question: 1) Our rooster. A red sex link mix. Under a year old. Developed either a cyst or tumor on it's back (pictures posted on another thread if you are interested). Was first noticed maybe a month or 6 weeks ago? Maybe a little longer. Got increasingly large. About a week ago, developed a sort of limp...one where he would stretch out his right foot before putting it down. Limp got worse, to where he was basically hopping around. As of the last 2 days, he is no longer mating our hens, and spends most of the day sitting in the run. He continues to eat and drink, but that is the limit of his activity. Tail is nearly always down when standing. We will be inspecting the foot tomorrow for bumble foot, but there are no outward signs of it (inflammation) on the top of foot or leg. Our guess is that the tumor has grown to a point where it is effecting his ability to walk, possibly causing pain in the leg. 2) Golden Comet hen. Under a year old. Less than a week ago, laying and seemingly healthy. All of a sudden she has become massively lethargic, largely overnight. Last night, so weak she had trouble jumping onto the ramp to get into the coop (eventually made it), and it took a few tries to get on the roost. Took her inside one day, put her in a small cage and tried to get her to eat. She did, but very, very little. Now spends her day, after walking out of the run, retreating to a bush and sitting under it. Basically all day. If she gets up to eat or drink, I haven't seen it. Shows zero outward signs of problems, as in CRD. Poop is bright green, what little I've noticed. No visible worms. Very frustrated. They are not only part of a "flock" but, darn it, we've come to consider them pets. Not like our dog, but of course we care about their condition. So...while ready to do the deed when necessary, I guess I'm just looking for advice on when it's appropriate. EDIT: As for the hen, there was another symptom...her neck feathers are strangely puffed out. We inspected her neck, but there is no actual puffiness in the skin or neck, it's just as if her neck feathers are puffed up and out of place. Very bizarre.
