So my styro hatch resulted in ~60% live hatches...but since being put into the brooder, 8 have died. All failed to thrive. All had leg issues.
I hate young chicks, they are so uncaring. They sit on non-thriving chicks to get warmth...its a very pathetic site. Please appreciate my chicks are not my pets, they are for food or sale, so I live by the creed they thrive or they die. But it sure sucks to see so many die. Out of the 21 who hatched, I have 13 that are healthy...they still haven't figured out how to eat from a bowl yet (they are 4 days old), but at least they are drinking and very able to move about. Right now there are 4 who are simply lying on their sides, being flattened by everyone else...and slowly dieing. I know, I could do something with electrolytes, but honestly, these chicks won't open their mouth for me. I tried an egg yolk but all that seemed to do was actually seal their beaks closed...
All of these birds were intended to be meat, hens at 10 weeks, roos later...so their genetics doesn't matter...but all that have failed are also chicks that hatched on day 23...I ran this styro hatch as close to 100.5F as possible, low humidity but not below 25%, and it has sucked. No egg was older than 8 days when put into the bator, and all had been turned regularly before being set.
IMO, nobody should try a hatch in a stryo bator, it can't give you better than 50%. And seeing this chicks with all these leg/foot problems, ****. And fwiw, adding electrolytes to water only helps if they can stand and drink, and all that have died couldn't...they stood with their heads held up, never thinking to lower their beak into anything until they fell over, at which point their only goal was to stand again, not drink, or eat, or peck, or anything. This electrolyte idea may work for pets, but it doesn't work for chicks expected to work for themselves.
I didn't take pics of the foot/leg issues. I checked, its not anything that was pictured on BYC when you search for foot problems, or leg problems....but it did sound like what people say when they aren't thriving.
I so wish I was not inspired to keep the styro bator running. I wish, when I got my brinsea, people had been adamant that I move my styro eggs into it. Since I have not had a hatch in it, I am only presuming it will do so much better, but I know styro hatching sucks for me.
For a styro, that's about a normal rate of hatch. However, the post-hatch results indicate a bigger issue.
Knowing what kind of leg issues, such as neurological (both legs physically normal but don't work equally), deformed (visible physical deformity), physiological (slipped tendons, red hocks, displaced hips) it's hard to know what is going on with your hatch.
What is your brooder temp at? While chicks and poults do tend to huddle on top of a flock member making distress calls, they should not do that for warmth. A brooder temp of 95-100 for starters will ensure that they spread out comfortably.
I've hatched a couple hundred chicks and poults this year in styro, redwood, and homemade foam incubators and have not had a single leg deformity from shipped eggs, from bought eggs, or from eggs from my flock. While the issues you are facing MAY be caused by incubator deficiencies, they may also be caused by brooding deficiencies, like not enough traction at hatch and during brooding to enable the chicks to get traction. The Brinsea hatch will help determine if it may be an incubation/brooding issue, or a parent flock issue.
When I raise birds for meat or eggs, every bird I bring to maturity or to market reflects a cash value. It's in my best interest to help them survive whether it means flipping them onto their bellies so they can get up, or giving them corrugated paper for the first couple of days so they can easily find food and get traction. For breeders, I do try to select birds that have no issues at hatch, but the cross I am making now is physically unable to hatch without issue. As long as they are on their feet in 24 hours and acting normally it's a success...weeding out will take place in gen 2. I need to build a big enough gen 1 pool to have a gen 2. Gen 2 will be a cross of like-sized birds so hatching should not be so much of an issue.
I do hope the Brinsea provides a better hatch rate, and the brooding success is in your hands. A mother hen will beckon her babies to food and water after a couple of days, once they are active just splashing in the water with your fingertip and tapping the loose feed on the floor paper should get them going. Once one gets it, the rest will follow.
