Go to Marnie and you can buy a heater for your coop. You'll also need to feed them hay everyday to keep them happy.Thanks I'll have to wait for spring again for them though. Switched games but finding this one equally frustrating at the minute trying to get Caroline to 2 hearts to get the tea saplings. She was very rude about my last gift that according to Wiki she likes! ..and got a coop full of grumpy chickens and ducks cos its winter and they wont go outside cos its too cold! . .don't think I'm cut out for a farming life!!
What did you try to gift Caroline?
