Actually, I've had my serama mixes get into the LF (Large Fowl) pen. While I never saw any sort of copulation, I did find them alive, and with zero scratches. To be perfectly honest though, I don't know. I've heard many people on here (or read, I should say) having their bantam females mating...
They can, and in some (or most) cases, the male can get the deed done. As you're probably tired of hearing chicken people say, sometimes their offspring are medium sized, sometimes their on the smaller side, sometimes on the larger. It depends
The short answer, yes. Long answer is, I don't have any experience with it myself, but I've read multiple times that it's very common. What I do have experience with is a serama male with a bantam hen. Sort of the same thing, but on a smaller scale.
Cochin bantams make wonderful broodies, I've...
Nope. I had been keeping chickens for 11 years before I had my first broody. Before that I had one borrowed, and that was unsuccessful. Red Sex Links will almost never go broody. At least mine never did. I have seen some that will
Yup. Although she'll stop laying for a few weeks either way. Although she'll usually return to laying sooner if she's broken right after going broody, as NatJ said
Yes. Although the hens response differs. Sometimes it's "you're right, this children business is too complicated", and others it's "F you, I'm having babies"
A good rooster/male should have a have a present role in raising the chicks. While not something I've experienced, I've heard stories of roosters taking the youngsters under their wings after the mum(s) stop mothering them. All males will know if one of their females is broody
