Broody hens help
The questions I would have are
Do you have a rooster? (I know may sound like a silly question but believe it or not some folks think any egg can hatch. Even college educated folks where I work.)
Do you wish to hatch chicks out?
If so I would let them sit eggs. If you do not have a rooster and the silkie has already sat a long time as it is are you willing to give her a couple chicks from a feed store and see if she will adopt?
If she rejects them are you set up to raise them.... heat lamp, brooder and the other needed items?
If you do not want chicks now then perhaps a broody breaker is in order. Now that being said both the silkie and cochin breeds are prone to being broody...... VERY broody. It may be worth it to get a couple chicks and let her raise them then sell them or keep them.
The cochin that I have that is a broody monster is not willing to accept chicks so will be given purchased eggs as I have no rooster.
Very broody breeds will sit on an empty nest once they reach that catatonic state of being broody.
How old are the chicks you have indoors? If they are only a couple days old you could try and get her to take one or two. Best to do at night from what I read.
My broody monster sat an empty nest for 8 weeks before I broke out the broody breaker last year.
If you decide to buy her a couple chicks they do not have to be silkie chicks. From my understanding of the breed they will raise most any chick. Not all are willing to accept chicks they did not hatch but silkies are said to be one of the most willing to adopt.
All broody hens stop laying eggs while broody. They would have laid a few to a dozen then decide to sit and the laying stops. It is a hormonal thing. Not her choice really but nature at work to increase the population.
I never expect eggs from my cochins so getting any is a bonus. I love them for the silly little chickens they are.
If you have to or decide to use a broody breaker there are a lot of threads on here about breaking a broody hen.
