I have been doing all of mine, but someone told me they only do their cria.
So what do I do? The bottle from the vet only gives me the amount for cria. Last year we used paste, but got to the end of December and sadly had a little female cria go down with rickets, even though I had been giving them the paste monthly since the end of September! So on the advice of the vet changed to injections.
So any info on who I give it to mostly gratefully recieved.
