Hi, this is my first ever post so I hope I have it in the right section. Yesterday I bought a second hand chook house off trademe (your craigslist) and it came complete with 14 x 2-4 year old hens and a rooster. I have rubbed their legs with vaseline as they looked a bit 'horny' and have dusted them all with Pestene for lice etc. They are isolated from my girls and look healthy except for feathers worn away on their backs I guess due to the attention of their rooster.I will repeat the dusting and vaseline in a week. The house has been waterblasted and today will be sprayed with ripcord and then sprinkled with Pestene. My question is.....what else should I do to prevent disease? Thank you very much for any advise.
