My hen I showed you Steph has always gone out with more agile breeds ever since she was a baby so she automatically does what they do.
She will fly to the roof of the house no problem and the shed roof is a piece of cake for her.
They are, in general, awful flyers though and I can’t see her ever getting up with the homers and doing a circuit in the sky around the shed.
Because she follows the others around all the time she probably doesn’t have as much body on her than your birds.
Bath time earlier in the year!
