Hi 5sandown
Sounds promising! But bear in mind that often the courtship circling doesn’t lead to mating, particularly if there are last year hoglet females around. Some mature females (who may have hibernated late because they had hoglets) may not even be back from hibernation yet. So, often the hogs around, at this time of year, are males and younger females. Usually last year’s hoglets are not old enough yet, but that doesn’t put the males off practising their courtship techniques! Sometimes a male will attempt to mount a female, but mating is not going to take place unless the female co-operates. Sometimes one or other of the hogs involved will just wander off, even after hours of circling (and even with two mature hogs) – it’s a wonder they ever have time to produce hoglets at all!
Bear in mind that normally peak hoglet birth times are June and July, with gestation being about 4.5 weeks. Although with hogs exceptions can never be ruled out!
