Pretty girls!Ah, Yessss! Thanks so much for sharing your information and experiences!! Very helpful indeed, my friend!!
I’m excited; I’m gonna go with placing some chicks in with them this Spring. I really like the idea of adding in my choice number of females with no roosters as well. This way you raise exactly what you want to have in your flock.
I order day-old chicks online using the post office, Hatcheries like to add in an extra chick or two for more warmth, safer travels, or even in case one doesn't make it. I’m happy I have a few family-friends on farmlands who can take a few extra pullets or roosters.
I already know who will likely be the best Broody, my Princess Buttercup. She’s always been the toughest to break and she’s really sensitive to others hormones levels. If another bird goes broody and doesn’t break fairly soon, I already know Buttercup will be my next broody girl, right away — guaranteed!! Ha!

This photo is from last Winter and on a very Windy 🌬 day, apparently… But, these Silly girls did not care one bit. They were 5 to 6mos here and were just starting to lay their beautiful eggs!
I don't use hatcheries anymore because of heavy losses, but if you are comfortable using them, then by all means.

Keep in mind that not all broodies make good mamas, but Silkies seem to be made for it. My tiny Silkies have raised Spitzhauben, Naked Neck, Orpington, Legbar, Easter Egger... So you can have them raise any breed.
Enjoy!
