I hope to breed my own some day, with a broody hen to do the work. That would be the best, IMO.
I would much rather start with chicks. Yeah, more work, but I wouldn't want to miss the incredibly CUTE part of chickens.
I'll be getting more chicks this spring/summer, and I'll see how the integration goes. I would guess, since I've never done an integration before, that 4 week old chicks would be easier to integrate than started pullets...? Maybe seem less threatening to the hens here now? I'll be doing a "look don't touch" for sure.
And then, with chicks, there is the CUTE factor. Aw, geez... so cute.
