Hi all, I’m just wondering how long I should keep my 9 day old pigeon in the incubator for? I have a small bird cage for it for when it’s ready to go there, I’m just not sure what the age should be for that. Tia :) I don’t want it to get too cold if it’s not ready

They've gone from this

Ok, so I have been feeding them properly just like someone told me to on here, they are eating Kaytee exact...They are about 15 to 17 days old now...do I keep feeding them the Kaytee exact? When do I start feeding them different foods (solids) and how do I get them to eat it? I'm super confused...
