I am now down to three hens having recently lost two and initially decided to add another three. Now I'm in two minds.After observing my birds over the last week, they seem really content, and I'm worried about upsetting the status quo. I'm fortunate that I work from home so if I did go ahead, I will be able to keep a close eye on them during the day. What are your thoughts? Should I just leave them as they are if they're happy, or would they be even happier in a larger group? I want whats best for them, and not what I think will make me happier.
