I have 3 laying silkie hens right now, of those 3 two went broody - one started in june the other started in July. Snowball my white sat on 6 silkie eggs from the 3 of them, and dutifully sat on them through heat, rain, etc (in the coop) and hatched out 4 beautiful healthy chicks and is the most dutiful mother to them now @ 3 weeks old. Taffy my pale buff hen went broody right about 4th of July so I ordered some Mille Fleur eggs for her to sit on, and of 11 shipped eggs she hatched 9 but only 8 survived. She hatched them out Tuesday, (3 days early!!!) and she had to endure 100+ temps, crazy humidity, etc. and like someone else said - she didn't never pant or anything. Both my silkie girls were good with letting me check eggs, move them, candle the eggs, ect...Until they started to hatch, once the babies started hatching and now - when babies are under them - hah my hand gets pinched and peck. They are GREAT mamas. Taffy just took her brood of 8 out for the first time this AM when I opened the coop up and let them out to free range. So very cute!
Silkies and cochins are the best broodies, and I highly suggest if your not interested in breeding them, atleast get you a couple hens to brood other eggs.
