As of 3 years ago I was new to chickens and guineas. I have bought from Alan every year, not a lot but we just wanted the eggs for eating. Out of all the chicks that I have bought from Alan, the only ones who died were the owners fault. Yep, mine. The guineas seem to prefer living elsewhere as I can't seem to keep them home. We have a neighbor way, way, wayyyy out behind us that has guineas and I'm sure they are surprised when extra guineas show up.
The one thing I am impressed with is how healthy Alan's chicks are. I have had no problems raising them or after they were grown. That is the ones who have survived the sneaky predator that lurks here now and then.
Last year in March I bought some Ameraucana chicks from Alan and told him the story of how one chick turned into a beautiful hen, then turned into a gorgeous rooster, only to have that sneaky predator get him before he was old enough to be a father.
Last year I also bought 2 Crested Polish from Alan and named them Elvis and Phyllis (Phyllis Diller). Unfortunately, Phyllis was Elvis and Elvis was Phyllis and we lost Phyllis to the sneaky predator. This year I have incubated 31 chicks of which some have a little puff on top of their heads, I can't wait to see what they will look like as adults but none of them will have the do that their father has. This year also I bought 3 more Crested Polish from Alan along with 3 more Ameraucana. He gave me a free chick and unfortunately, two of them got into the water dish and one didn't make it. Like I said, owner's fault.
