Whites generally have bigger crests than other colours anyway, so that is probably why they were okay. Type isn't great on them, but they are a great deal better than some hatchery silkies I've seen!
So if recommending a hatchery if you HAVE to get a hatchery chick, Ideal is better than McMurray?
Yes, I know. I am very close to the Ideal Hatchery in Cameron, Texas, so all the feed store chicks and TSC chicks here are from them. I haven't had any dealings with other hatcheries. Maybe some others can post experiences with them.
If I were going to recommend any, it would be the white chicks from Ideal - just from my own experience. If you are buying them from a feed store you can visually inspect them, check feet, etc. They are already started on electrolytes and medicated chick feed also. If you are ordering direct from the hatchery you don't have that option, but I know a lot of folks buy them like that.
