The 45 centimeter fence has kept the young man away :) What time do you consider best for x-raying the females? In 50-55 days after the suspected impregnating? I think that two of the females are ok, but of course the most fat looks like she could pregnant :/ She hasn't gained any weight but her stomach looks somehow different. Hopefully I'm just paranoid. Anyway I want to check all of them with x-rays to be sure and to know how many pups to expect in case (when) the is some problems with delivery.
