NR360? I made diy hatch bags for mine. I'll get a pic later if you want. I've got 22 in lockdown. 8-7-7 Separated 2 of the 3 hens eggs.
Your little one looks like a Blue Copper to me...? 🙂
Edited to add... super small zipties for leg bands help after pulling them out. In case you needed to...
How's your hatch going? I've got 22 of my BCM's eggs going into lockdown today.
Mine are from 3 of my hens, and in doing a search on 'hatching bags' to separate them, your thread came up.
I've been running 25-30% for the first 18 and shooting for 60% during lockdown.
Good luck with your hatch.
