I can only share with you what I have learned and experienced with my button quail hatchings, although years ago, I used to raise chickens. Please keep in mind that I am no expert, and I don't know what kind of quail you are raising, but here is my 2 cents worth of advice on caring for [button] quail after hatching....
1. Add a vitamin/mineral supplement to water dish. If your quail eggs were shipped, you may not know the conditions under which the breeding pair were kept. If there is a vitamin/mineral deficiency in the mating pair, any eggs produced will also lack these nutrients to hatch and develop normally. For example, a lack of Riboflavin in a breeding pair can result in chicks with leg/foot deformities. Therefore, supplementing newborn chicks with these nutrients gives them a better chance of surviving if they are lacking a particular vitamin or mineral.
2. Add probiotics to feed or water. I use PB-8, but there are many other probiotics available out there made and marketed specifically for chicks to help rid any overgrowth of bacteria that can cause them illness. Also, watch for droppings that adhere to a chick's backside and collect there into a large mass. This condition is fairly common, and it can cause constipation and illness if left untreated. You can help to eliminate it by giving a chick probiotics (orally) and gently cleaning its bottom with a Q-tip soaked in warm water (this will also help the chick to produce a bowl movement and further rid of any constipation that may be causing it weakness and/or lack of interest in feeding normally.)
3. Watch new chicks closely for signs of overheating. If they appear to be panting, laying flat or on their sides with legs stretched out away from their body for long periods, or scooting off into corners in your brooder, then the heat from your brooder lamp is too intense. On the other hand, if they are piling up on top of one another directly under the lamp, or standing high as though they are lifting their body upwards towards the heat source, then the temperature in your brooder needs to be increased. I really don't go explicitly by temp readings as much as I do how the chicks are behaving.
4. As others have stated, make sure that your starter feed is ground to almost a powder-like consistency. If the pellets are too large, they are unable to eat enough, even if it appears that they are pecking at it. Spread this feed freely all over the brooder so that they can find the food easily by simply pecking at the ground around them, rather than having them search for the food dish. They will eventually be able to recognize the food dish, but it will take them 2-3 days after hatching to do this.
5. More on feeding....you have to show them how to eat. Use your finger to poke around at the bottom of the brooder. In this manner, you are replicating the behavior of a mother hen and teaching the chicks to peck at the ground for their food. Some chicks instinctively know how to forage for feed and peck at the ground right after hatching, but others will literally starve unless you show them how to do this.
6. Observe them to see that they are finding and drinking water while in the brooder. Add bright red marbles or stones to attract them to both the feed and water dishes. If you observe them not drinking enough water - or no water at all - in the brooder, you may need to use a small dropper and dab water on the side of their beak for them to swallow. Again, like the feeding mentioned above, some chicks need to be shown how to eat and drink. It's important to dip a chick's beak into the water dish when you place them into the brooder for the first time -- this insures that the chick gets hydrated, but also teaches them where the water is located.
7. Emergency Fix: Just a warning about this, as some may find this controversial due to the fact that this remedy won't be found in website or book sources. This is information gained from a local friend who has raised pheasants for over 20 years, and I can only offer my experience with this remedy by way of stating that I believe it literally saved two of my own button quail chicks. The following is a remedy for chicks who are weak, star-gazing, walking backwards, and/or near apparent death with convulsions (seizure-like behavior) when all else has been tried....
Mix the following:
- 2 Tablespoons of filtered or distilled room-temperature water
- 2 drops of "Trace Minerals" drops (available from Whole Foods or similar health foods store, sold in a blue bottle)
- A full pinch of granulated sugar
- 2 drops of avian vitamins (or Poly Vi Sol without iron)
Use a dropper to apply to side of bird's beak, and repeat once every 30-45 minutes. I found that my two button quail began to show quick improvement within 45-60 minutes, with this solution providing them with the energy they needed to peck at food and to stand upright, eventually regaining strength to function and feed on their own within a time period of 2-4 hours..
Sorry so long, but hope this helps you somehow. There are some great folks on this board who have raised quail for years. If you can describe more of the symptoms you are noticing, they are pretty quick to get on top of it to provide you with some great advice. So, if you could observe and describe any other symptoms, please add them to your post.
