If there are any serious daytime predators it takes a very serious run to keep them out. Goshawks are particularly difficult because they will hammer straight through chicken wire, often injuring themselves in the process. Daylight hunting foxes are just as dangerous. Thankfully, here the chickens can run for cover and mostly they make it. Given the number of hawk strikes we have here (it's been about two a month that I know about this year) the chickens do very well. If Mel had been in a run she would be dead now.
This isn't a good place to keep chickens. If you lock them up tight enough to keep the weasels and hawks out the chickens are in prison basically. It's always a hard call I find but I would rather they were free.
Poor Lavender. She was moulting as well as broody & a not very happy chicken. The bantams normally like to get under her fluff & pretend they are chicks again but as they were also broodie they were having their own issues! 
you're a trooper hanging in there!
