We had 4 covid chicks. They self-sufficient if you left a large feeder and enough water, a 5 day vacation was no problem. Watch out for too many eggs stacking up because its ugly if they start breaking them. We didn't have a rooster which only caused 1 setback. 3 of the chicks revolted against the alpha ganging up and hurting her pretty bad. We had to find a new home for that one chick. I guess roosters prevent that type of thing, but I wouldn't have done it differently because roosters are a pain in the ass.
