I had already ordered 7 day old chicks(4 White Leghorns, 3 Golden Buff (red star)) to be delivered the week of Nov 3 when I found some Delaware day old chicks that would be available the week of Nov 12 and ordered 7 of them also. Will I be able to brood them together or should I keep them separate? My brooder is approximately 24 sq. ft.( it's in my home office). I could put a chicken wire barrier between the two groups if necessary.
