I started something new this season out of necessity that has turned out to be a real boon.
In past years, I'd sanitize the brooder, feeder and watered between hatches and use only fresh new bedding. Every batch of chicks started well, but once they hit the coop, which has been occupied for 12 years and never sanitized, they'd all come down with cocci and needed Corid in their water for weeks. I'd also lose a turkey or three as they are more susceptible.
Now I just scrape dirty bedding from the last batch, top off with fresh, and put new chicks and poults in the semi-clean brooder. I also put the smallest bird from the previous hatch in as life coach when the new ones are 2 days old. This older chick or poult will shed cocci and infect the babies with the strain found in my yard when the young ones are in "taste everything" mode. Oddly enough, they generally have a day or three of loose stools then go back to normal and have no further issues unless a new strain comes in. Then I treat the water as long as necessary.
While I can't guarantee the same results for others, it's working well for me.
Thanks for explaining. I also don't completely "sanitize" the brooder, nor my "baby coop". But I do like the idea of keeping back the smallest from the last hatch as a coach.
Also, this question came up last night.... how often do turkeys "mate"? I mean, I know roosters are on the chicks several times each day, but are turkeys that active?
