My girl went broody this year and hatched 4 so far. If its contagious she probably picked the behavior up from my light brahmas. One just had a successful hatch.
I have a silver spangled hamburg named Sammy who does not stop crowing. But it's soo funny when I interrupt his crow by scaring or spraying him wih the hose. He runs off screaming. Too funny
Just relax, these things take time. I had to take down all the perches I put up in the run cuz they would not go in the coop at night. Now I have a ton of perches in the run & all my girls go to bed at night.
Just expect the sweetest 1 to be considered the weakest 1 and will be at the bottom of the order. That will change when you introduce a new group of chickens and it will start all over again
