Green Cheeked Conure - Chicks

Three out of my four Green Cheeked Conure chicks have came out of the breeding box. There have been some big differences as opposed to my Indian Ringnecked Parrots. Firstly they have been very staggered when they would come out at least a few days between each one unlike the Ringnecks that all come out within three days (I guess more related to staggered hatching). Secondly the conures will go back into the box after emerging something the Ringnecks simply did not do, once they where out they where out.
