Here in the UK they are called nappies. Cannot imagine even attempting to put our hens in nappies - the cats would never let them live it down!
Our 3 girls do come in, led by Henrietta, but we try to keep them out of the bedroom and drawing room. We live in a bungalow! Any accidents are easily cleaned up and if we do have to bring one or more indoors, they get popped in the puppy pen with plenty of straw, water etc. The cats keep them entertained and the hens reciprocate, all is well and calm and happy.
Funny story about our beautiful, and sadly late, Alice. An Australorp hen, she was murdered last month by a rogue dog. One day my disabilities decided to remind me that they and I are well attached to each other, so I was having a rest on the bed. Hearing gentle clucking I spy Alice and Henrietta in the hallway. Happy that they were ok I dosed off. Imagine my surprise to open my eyes and discover a hen very contentedly sat next to me on the bed. I moved to put her back on the floor when she decided to have a quick flap over to my dressing table. There she stood in front of the mirror, admiring herself! First she looked one way and then turned to admire herself from another angle. This continued for a couple of minutes, until I disappointed her and put her back in the hallway. At least she knew why we always told her she was so beautiful, she'd seen for herself.
Just wait until Daisy and Clementine decide to do the same thing! Daisy is a Marsh Daisy x Light Columbian Brahma Bantam and has the Marsh Daisy colouring with the Brahma feathering, so incredibly beautiful. Clementine is a rare Citrus Campine, so equally beautiful. You can imagine the 'conversation', along the lines of "Mirror, mirror on the wall, who is the fairest of them all?" Henrietta, by the way, is a lovely Barnvelder, who is sweet natured and loves cuddles. She had her picture in Practical Poultry, with our ginger cat Edward, so has her own 'claim to fame'
