I've paired my pastel female 6 or 7 times starting in November till now, observed locks every pairing, male is producing plugs. The female has put on 800 grams since November but I have not seen an ovy ( I'm also not much good at palpating), and she has not went off feed except for two weeks (back to back). I introduced the male again tonight and instantly she started tail wagging. If she is still tail wagging is that a sure fire sign that she has not ovulated yet?
