Hi- I am posting for missychicky. She has four three + old hens who are being very lethargic. They are staying in their coop all day. Mostly they either roost in the run or roost in the coop. The coop has a 60 watt red light in it to keep them warm. We are in Oregon and it has been rainy, windy, and overall nasty. At the moment the temperature is 45 degrees and they are huddled in the coop. They still eat, and they seem extremely thirsty. Their weight is between 4.5 to 6 pds (as of several weeks ago). They are being very quiet - and we have Austrolorps who usually are EXTREMELY talkative, and they do not seem interested in much, I offered them a worm and they were more interested in huddling . Their poop is brown and runny. The head hen (Jasmine) is molting at the moment, the other three finished molting recently. They were wormed about 2 months ago and they usually get ACV water (I don't think it is at the moment) We are not sure if they are just old (nobody is laying anymore :-( ) a little cold, or something else. I plan to get them a heat lamp as soon as I have the extra $10.00 to do so. Should we be worried or is this just old age in chickens? Thanks for the help.
