Wry neck and spray legg often

[getaclue]

While wry neck is typically a nutrition problem, splay leg, and curled toes tend to indicate temperature fluctuations. It's fairly common when incubating eggs.

Cut back on the treats, especially prior to hatching. When breeding to select eggs for hatching, keep them mostly on their feed. If you are going to treat, I would suggest canned mackerel, tuna, any cooked meats, mealworms. These boost the proteins a little, which is good. Don't overfeed on the treats. The equivalent of a couple tablespoons per bird, no more than every 3 days is more than enough. Salad ingredient type treats are fine after you've bred, and selected the eggs you want to hatch out.

IF the problem continues after you've cut out most of the treats, I would be suspecting the feed. More than one person has found that the nutrition listed is not exactly what they're getting, or the feed is older, and depleted.

If you answered these questions I missed it.
What breeds?
Any chance of inbreeding? (i.e. full brother/sister mating)
What is the percentage of hatchlings that have these issues?
Does the feed have a guaranteed analysis tag on it?
Does the feed have the mill date on it?

My experience with local co-ops that mill their own feed is that they grind grains and legumes with a general assumption of the average nutrient levels that are in those ingredients, then add a vitamin/mineral blend in a quantity commensurate with the quantity of bulk ingredients. Many local mills have quit that line of work because they can't produce enough feed to use those supplements before they expire.
Hence the reason I was curious about the guaranteed analysis tag. In those days they made an educated guess but didn't really know for sure what was the end result because they had no lab to do an accurate assay.

Good information ChickenCanoe. Even inbreeding for 1 generation should not cause the described problems.

I'd really like a brand name so I can look up OPs feed.
