Hi iv had that problem with my sheepy/fuzzy they are sooooooo hard to sex i sexed 5 wrong as boys as i couldnt see nippels and they had a buldge which looked like testicals so i kept them in with boys then one day i looked and they were in season and had been mated as the male had left his plug then i knew they were girls, it is easier to sex them when they are really young about 3-4 weeks but yes the one in the pics looks female.
