I only have two females but this time of year, every august, the one becomes broody. It's fine if I am here as I can make sure she goes down to eat by locking her out of the house so she can feed but I am going away on holiday next week and I usually pay someone to come once a day but at this rate I will have to pay for two visits to make sure she is locked out of the house to eat/drink as she isn't bright enough to make sure she eats, she would just do her lion puff out all day until she starved to death 
I put an icepack under yesterday but she just made it warm! and really was not bothered by it.
are there any other tips? I read the advice about the wire cage and fan but tbh i didn't understand it 
any advice appreciated thanks. i most probably worry too much about my hens but I don't like the idea of her dying because she has forgotten to eat whilst we are away on holiday either
