I have several royal Palm hens about 9 months old, one of them has started to lay in a corner of the goat shelter. there are 4 eggs so far, its been a 3 or 4 days & no new ones,i was worried that they would get trampled by the goats, so i built a flat roof over them leaving about 16 - 17 inches under for turkey to go under. Question is will she continue to tend them or abandon them because of the change( roof)? I'm not set up with an incubator, I'll need to build one. also how long will they last without her tending them. the forcast is freezing temps in 44 or 5 days. Any input would be greatly appreciated. thank you.
