Fairly new to chickens here My adult SLW hen has been acting strangely today. She has seemed anxious and stressed out. She's panting a lot. She's not foraging with my other hen. Shes made many unsuccessful trips to the nesting box. She's also been going behind places (like my large trash can, trying to get behind the bin that holds pine shavings, etc) she's still drinking and eating somewhat. But she's just off. Could she be egg bound? I picked her up but didn't feel anything. But I haven't had to do this before so I don't know what I should feel for. I should also say she's not fond of being handled. We rescued her. She's usually my best layer. What should I do?
