I'm new to this, so I apologize in advance if this is common knowledge, never a stupid question, right?
I got 3 Buff Orpingtons a month ago for a small urban coop and run. They've been wonderful, exploring outside during the day (I can see them out several of our windows, so I spend an inordinate amount of time watching them
) and roosting normally at night. For the past couple days, though, they've begun to spend their entire day in the coop. I'll go down to visit them and they'll come out as soon as they hear me, but return to the coop as soon as I walk back in the house. I put small water and food dispensers in the coop as I was worried they weren't eating or drinking since they're spending all of their time indoors. Should I worry? Are they preparing to lay? Or did something frighten them?
Thanks in advance for your help!
