Jen,
You have outs. I am not going to comment on you selling anything now. As it has already been posted by many. But you have outs. here they are.
You want to continue to breed. You want to continue to keep the animals you have. And you have stated that a few breeders have offered you snakes for nothing. This to me tells me you have outs.
I would seperate the animals you have now. I am not 100% on how this virus works as you have said it is new. So I would get another building or place to keep them or the new animals you have been offered. If it were me I would not be keeping the "infected" animals in the same building.
But you have an offer from some very kind people to help you out and get you back to where you say you once were. So you say you do not have the money or will to rebuild but you have some great people guiding you?!?!
The other way to go is step back for a few years. You now have babies to grow up to see how they react. Right? This will help in the studies about this virus. Come back once more is known.
I read your story. It sucks. I would not wish it on anyone. And I know you would not either. That is where some are coming from. There is a risk no matter how small it is when you sell them babies.
Talk to these fine people that offered you snakes for free. Work with them. I would find a new place for the new snakes if it were me. New cages and everything. That is me.
The steps are there Jen. All you have to do is take the first step and then the next. You will be at the top soon enough if you do not skip a step.
Good luck
Gary
