Liz, That is really small. I have 6-7 month olds that are over 30grams. An adult male should be around 50-60grams. I recommend not breeding him to anyone till you are sure his hookworms are gone and he puts on more weight (which may well be till next season). You are just asking for problems otherwise. You should get another fecal done a few weeks after treatment to make sure he is clear of worms. Rayne should also be checked since you bred them; he could have very well spread it to her or anyone else he came into contact with -Mike.
