Our flock has dwindled down to 2 birds, they are both 5 years old and Americana and Rode Island red. We are looking for a new flock for them to join, but Dotty, the red, has become lethargic for the last 4 or 5 days, just since the temp dropped. She is still eating and drinking, has had poop on her feathers. We have given them probiotic and she was looking better yesterday, but when I let her out today she just stood around, keeping close to Hawk the Americana. We have not quarantined Dotty since there are just 2 of them and are worried more about them being alone. The question I have is should we bring them both inside overnight to perhaps get dotty warmer? Will it make a difference?
