Yes, I agree, breed from the strongest. But... this is where my opinion differs from main stream. By basing the definition of "strongest" on hatching performance, we're only looking at a very small sliver of the pie. And, I'm in no way saying that folks who let the chick who needs help out of the shell die are NOT looking at the whole pie. I know that most of the folks who are hatching eggs are also culling within their flock, so they are constantly looking to see who stays to play in the gene pool an other year, and who goes. So much criteria to look at, even for the back yard breeder with a barn yard mix.
So, hatching performance is a small, but important piece. The question that I continue to ask is this: By letting the chick die in the incubator, are we truly culling our flocks for future hatching strength? Common sense says yes. Now, look a bit further, and ask, "Why is this particular chick having difficulty getting out of the shell?" I'm left questioning my skill at providing artificial incubation that matches the needs of the chick all the way from embryo to hatchling. At best, it's an artificial means. We all know that a "good" Mama Broody does it best. Even a Mama broody who's never seen a chick before, never incubated an egg before is capable of hatching eggs in far less than ideal circumstances. If Mama got a parade for successful hatches, she'd be getting one with every clutch she sets, I imagine! So, I have an inferior incubator, I make mistakes, errors in judgement, temps and humidity are not always perfect. For that matter, we most likely still don't know what perfect is. Then, look at the eggs: genetic flaws... hopefully, those are the ones that die no matter what we do. Then, there's nutrition. I tried an experiment where I had my flock on supplemental vitamins in addition to high protein. I figured that would improve my hatch rate, right? WRONG! Worst hatch ever! Chicks did great right up to lock down. Then, I had the highest percentage of DIS ever. IMO, these chicks had too much of a good thing going. They grew too big to be able to position for a good hatch. So, I'll continue to be of the opinion that a chick that is the result of an assisted hatch, CAN grow out to be an important contributor to the gene pool. It's no fault of the hen who laid the egg, or of the chick if he's too big for the container he was given to grow in. It's no fault of the hen or the chick if the temp or humidity is off, and he ends up being glued, or delayed. Just as human babies sometimes need to be delivered by cesarean deliveries, and they sometimes need to spend time in NICU, that does not mean that they are genetically inferior. We've all heard of the NICU baby who goes on to be a foot ball star, or is smarter than all of her class mates!
So, I'll remain red. I'm early in my hatching career. I may shift to the blue side in the future, and I absolutely understand and respect the "Don't interfere. If the chick is not strong enough to hatch, I won't assist, and I won't have to cull a little fluff ball later when he has problems." I truly respect that! But, I'll continue to assist as needed. I'm thankful that all of the chicks that I've assisted have gone on to grow well. 24 hours later, I can't tell which chick was assisted, and which one was not.
Excellent points! So you will be happy to read my last post, and you also make me feel better for what I'm doing. Yeah!!
