I currently have 22 baby quail about 2 weeks old. 2 of them are not getting bigger but are alert, eating, and don't appear sick in any way. This is my first time with quail, they are technically hubby's project but I am the one that cares for them. Would it be best to separate the 2 smaller ones to see if they thrive better, or leave them all together? I recently moved them into a much larger enclosure.
