I am a private breeder and have bred these myself. I have incubated for female but it's not a
100% guarantee. All have correct paperwork ( article 10's) and have been fed a natural diet of weeds and wildflowers with regular use of calcium supplements.They Have been outside this summer when weather permitted and are all very active and feeding and growing well.
Advice on care and setup given also caresheets and chalk block with a sample of pre-alpin (I use this for extra fibre in their diet).
