All of the breeds you just mentioned have high prey drives which would need about the same amount of training and socialisation to leave the birds alone. I'd also be careful about reccomending bcollies to anyone who isn't going to be training them to herd, or running them for hours a day with tons of mental stimulation. I think in this situation advising to only get LGDs in future is fair, since accidents are always a considerable risk with pretty much any other breed. But this is still only relevant when talking about in the future- as OP has already said they won't be rehoming the current dogs.
Having huskies and malamutes while keeping poultry is possible. You just have to be very careful. I have a husky mix and also a malamute, no close calls have ever happened. The only downside is the constant paranoia and double checking every gate and fence.
