Once she's out, she's out. She panics when I pick her up so chasing her around to recapture her is unnecessary stress.Well, the above is what I would do before I did anything else. I've first time moulting hens here that wouldn't come out of the coop. I very carefully carry them to an area I know is good forage and see how they behave. Luckily so far they've all started looking for whatever it is that they need. You need to stay with them and you need to be very gentle handling them because of the danger of busting a pin feather.
Have you ever seen staggering in first time molt hens? This girl was vaccinated for Marek's for whatever that is worth.
I know it's practically impossible to answer, but do you have any idea how long before she is through the worst of this molt? If they molt hard, is it fast vs molting softer and longer?
