We were all set to sponge our ewes on Saturday, with the tup booked in for 2 weeks time, in order to lamb when I have booked time off work. It sadly turns out that Chronogest is unavailable for another month or more. Is there another way to try and synchronise the ewes? Also if we just put the tup with them for 3 weeks is there a chance of getting any lambs at all? We only have 5 ewes. Many thanks.
