Hey, how did it go for your quail?
One of my Coturnix also started sitting on eggs - I was shocked as I believed they lost this instinct. I avoid any disturbance to her, but after 13 days that I stopped collecting eggs, she has 22 in her nest by now, as other hens would drop their eggs to her too

I'm worried it's too many but I would not know which are new, so just left her like this (I didn't have such a brilliant idea as to mark them).
I am also concerned if it's going to turn out well. It is Septemper, so here in Poland the temperature starts to go down - 18-25 Celsius degrees (64-77 F) during the day, 8-10 (46-50 F) at night. The coop where she has her nest is insulated and I set the thermostat to keep the temperature at 20 degrees, today turned it up to 25 (77 F) as I expect that hatching might start any day now, so worried it may be too cold for the chicks.
Do you have any advice for me? On one hand I'd like the nature to do the job, but then I don't want the 'aspiring mummy's' effort to go in vain due to inadequate care.
I wonder if I should move the quail to my house, increase temperature, anything?
Welcome any advice!
