I got 5 hens 18 months old from an organic egg farm. Each year they sell them off as a fundraiser for local nonprofits. I kept them quarantined, then moved them to the coop but kept them inside for several days. They've been doing well, and today I let them out for the first time. This evening when I went to shut them in, one has a swollen abdomen and walks like a duck... Trying to figure out if shes egg bound or got into something she shouldn't have and has ascites?
