I forgot to update this thread with my week 3 results so here they are but I must add that I have 8 chicks eating crumbles in a 16 sq ft brooder and 18 chicks eating ff in another 16 sq ft brooder and the smell difference is astounding! When the chicks were on my front porch, I think they were A) too young and B) too close to notice a difference in their smells but after moving their brooders in the garage, I can't believe the difference. I kept wondering when I would smell the nasty CX smell I kept hearing about and then it happened yesterday. It was supposed to rain so I didn't put them outside and when I went in to feed them later, I smelled the most putrid, rank smell coming from the crumble chicks. The ff chicks smelled, but it wasn't a rotten/dead smell, it was almost sweet but not revolting. I was surprised to say the least because there are 10 more chicks in the same sized brooder as the crumble chicks.
Day 22 6/19/12 Wed End of Week 3 Weights
Fermented Feed Chicks
Fed bucket #15
Total feed consumed to date : 108C
Total feed during week 3 : 60C, approx 18.75lbs
Weights in oz. : 14.125, 11.625, 15.0, 15.5, 15.75, 16.375, 17.375, 17.625, 17.75, 18.375, 18.625, 18.625, 19.0, 19.125, 20.125, 20.125, 20.875, 21.125
Average weight : 17.6181 oz.
Average gain in week 3 : 8.4101 oz.
3.3333 C eaten per chick, avg. week 3
2.5231 oz. gained per C feed
Crumble Chicks
Fed 4C toCC which were consumed before weigh in and 4 more after weigh in for a total of 66C on day 22
Total feed consumed to date : 62C
Total feed during week 3 : 29C, approx 9.0625 lbs
Weights in oz. : 20.875, 21.5, 22.375, 22.375, 22.75, 23.625, 24.75, 27.625
Average weight : 23.2345 oz
Average gain in week 3 : 10.5154
3.625 C eaten per chick, avg. week 3
2.9008 oz. gained per C feed
Conclusion:
This week, the CC have a better feed/weight gain conversion by 0.377 oz./C
Last week the FFC were better by 0.5017 oz./C
I did not get starting weights on the chicks at day 1 because I was too concerned with getting the chicks off to a good start and not stressing them out too much so for overall calculations I will use 0 oz. for day one to make things simple. Overall, after 3 weeks, the CC have a gain of 2.9980 oz. / C and the FFC have a gain of 2.93635 oz. / C. So, at this point both methods are virtually equal as far as cost. But, overall, the FFC have eaten 6C per chick and CC have eaten 7.75C/chick giving them a faster growth.
Starting at week 5, I plan on sepatating the FFC into two groups. Group one will consist of 9 chicks which will continue on the fermented crumbles and group two will consist of 9 chicks eating fermented crumbles and grains split 50/50.
