I posted more about my situation in flock management--"new flock/old flock...". I had a flock of 8 and 9 year old hens, two got very ill over the winter. Fortunately I have a neighbor who is willing to put them down for me. I have three left, and the consensus here has been that I should integrate the old flock with my new ones (currently 3 1/2 weeks old). One of the last 3 hens has been feeling quite under the weather for a while (months off and on, now all the time). She just sits around a lot. At times she seems rather active, and will come for treats, but most of the time she just lays or perches, with her tail down. I've looked her over, she isn't light, and there is nothing obviously wrong. Of course she is very sweet and sociable, my favorite hen. The other two are very healthy, one even lays eggs! I don't want to prolong her suffering, and I don't want to integrate her if there is a chance of spreading something to the new flock. But I'm happy to leave her be if she is just plain old. Would love some insight into her situation.
