I have a spider male that is 763 grams and producing sperm. I have paired him with two females twice each and I have not seen any locks. The females are 3 and 4 year olds that weigh 1784 grams and 2213 grams. I have misted them, put in another males shed, sperm of another male on the females back and I keep him in for 4 days! With the one female, I see her cuddled around him but no locks! What else can I do to get him going?
