Welcome darajosami .... This is a great site, and great Aussie pages to be found here, including this one. It's great to hear you are getting some chickens - they are wonderful to keep, and can be such a great source of fun and caring.
Speaking of which, and the main reason I am replying, I thought I had best let you know ( if you have never had Silkies before ) ... that they are very very prone to getting thoroughly wet through to the skin. Their downy feathers do not protect them like larger chickens ( normal feathered chicken feathers are thick, and the rain runs off them like from ducks ). I lost my dear little Silkie ( Moppitt is my profile pic ) .... to getting soaked in an overnight storm - where the coop leaked ( I didn't know about the leaking part at the time ) ... and she must've been wet for some hours. Came down with respiratory > pneumonia very quickly and succumbed to that. Of course the coop is completely rain-proof now, but all too late. My other chickens are ok ... but I will most likely not have another Silkie as I would be inclined to keep her / them indoors, and let them only out to free range on the nicest of days. They are really very fragile, but with good care and protection, would give years of delight and lovely little eggs.
Thought I should mention this ... to give you a heads up about keeping them totally dry at all times. Problems if you don't. And they don't get out of the rain too quickly either ( silly little sweeties ) ... Good luck with your brood of Silkies and any others you can raise when the initial lot become broody - ( and they do very easily ) or in the incubator.
Cheers ........ AB
