Good to hear you’ve looked through the forum, as you say the calciworms are best avoided. Are the hoglets eating the food alright? You can weigh them every so often to see how they are getting on. I’d be tempted to try them on some kitten food as well as the Spikes. The kibble is smaller so easier for small hoglets to manage, plus it’s full of protein and has a high calorific value. Keep us posted with how the hoglets are getting on.
