Where are you located? We had our largest "momma" crayfish drop a nice size brood of babies about a month ago.
We have around 100 baby marbled crayfish you can have for free if you come & pick them up. In order to give them the proper space, we had to let them grow-out in the guppy pond & they are big enough now to where they have started to snack on some of the guppies & we do not want them eating our stock.
We don't want to ship them as it is not worth the time nor do we have any shipping supplies so you would need to pick them up in Wilm., NC.
