One of my Icelandic hens seems to be making a real effort to hatch her (and probably her sister's) eggs. At first she was acting really boody, but she'd easily abandon the eggs to go play with the roo and other hen. The past two days, she's been on the eggs full time (I think; I'm at work during the day). Sorry if these questions are super basic, but I wanted to post them here in case there are any needs specific to Icelandics.
1. We are both new to this. Does she need to have food and water available inside the nesting box or will she eat and drink when she needs to?
2. If she leaves the eggs again, how long can she be off them before they become duds?
3. Should I try to check to see if she actually has eggs under her? I have one ceramic egg in the nesting box.
4. I'm hoping if she does hatch chicks that they will just remain in the coop with everyone.
5. I've marked my calendar for 21 days. How soon can I candle the eggs and expect to see anything?
Thanks!
