Hi, I wonder if you would mind giving me your advice/opinion on another matter? My hens don't dust bath and they never have although they have an abundance of areas they could use - when they were living in doors with us I provided them with a tray which they never used, I picked them up and placed them on the dirt - didn't work. Outside we dug them their own area to use but other than scratching for bugs, nothing. We are in the process of relaying a patio, where we have lifted the old slabs, there is an abundance of dirt mixed with sand so we have held off from laying the new slabs, hoping they might use that area, but so far they only scratching it for worms/bugs - there have been pigeons dust bathing in it and I'd hoped hens would copy but so far nothing. My worry is that because there are no other chickens, they have no one to learn from, they were incubator hatched and kept with all other duck and chicken hatching's in a brooder, then we bought them age 3/5 weeks so they have never met nor seen any other chickens, which I wonder if is why they don't do a lot of the usual chicken stuff. If you have any suggestions/ideas on how to get them to dust bath, I would much appreciate your advice
