It seems that my 2nd batch of eggs are late starters...LOL AND it seems mostly cockerels... I have them in a large large wire dog kennel separated with hard wire. The two sets of chicks are 6 days apart from hatching. I was going to wait until the new chicks are up and really going (maybe a few more days). I would like your advice when I can remove the hard wire that is separating them to integrate them safely together? Thanks
