I have a seven month old buff orpington hen that has gone broody with every single egg she has laid. Usually once I take the egg from her she just growls and huffs in the nesting box for about an hour afterwards, but today she has been in there all day long. I don't think she's eaten or drunk anything all day. she went in the box at about six a.m., laid her egg at about three and I took it from her shortly afterwards. It is now around six and she still has not left. I try letting her free-range, which she normally loves, but she went straight back to her box. (Even though there is no egg there.) I tried putting an ice cube under her, but so far she's just sitting on it like it were a normal egg. Any suggestions? Thanks!
