So funny i have two Buff Orpington hens that are tag teaming about 23 eggs in the community nest. I broke them up tonight though. I candled all their eggs there were and 20 showed growth. I gave each hen 10 eggs each. I built a cage around the community nest box and put 10 eggs in the single nest box right next to the community nest box. Amazing both hens took to sitting as soon as i put the eggs back. I'll also put a cage over the single nest box if i find shes still sitting tomorrow. If all goes well I should have chicks the 1st and 2nd weeks of February.
