My daughter was going to have two pet house silkies, but our barn cat managed to get inside, get past dad, and killed one before dad could react/stop him.
Since that happened, we had a baby that hatched on the same day, who I've named star.
Star and Rexi are doing very well together. Rexi is going to be 3 or 4 weeks on monday. (I can't remember the exact week. haha I'm terrible.) Rexi's a little shy, she was in the brooder when Sally was killed, so she's been skittish since then, but she's taken Star under her wing and mothering her. She showed her how to eat, how to get water, and she sits on top of her to keep her warm.
Any suggestions on a good cage, as they get older? We were thinking either a parrot cage, modified or a rabbit hutch.
If you are using the housing only for sleeping/laying eggs purposes than anything you use will be fine. Silkies will be happy to roost/sleep in a plastic nestbox. I use a sturdy Homz Kidz box as a nestbox inside a 4x4 dog kennel that has a door -- the only color these Homz Modular Storage come in is black now and Walmart still has them online for approx $18. These small Homz Modular are getting scarcer to find but are a perfect size for a Silkie to sleep, and straw or egg doesn't roll out -- I recommend 2 boxes for 2 Silkies:

Our in-house chickens are only inside during quarantine or illness so we never have more than one chicken in the house at a time. We have the kennel but allow the chickens to roam the house if they want - I close off rooms I don't want them in and we have tile floors - no carpet. I hope your two Silkies are not a boy and a girl otherwise the boy will over-mate the single female. 2 females or 2 males would be good but not one of each for the sake of not having the female worn out from one randy male.
