You won't see problems, if any, in the short term. It's a long term issue so I wouldn't expect any issues to crop up this soon.Chick feed prices jumped way up, so I’ve been feeding layer crumbles this year cuz they were way cheaper. Haven’t seen any problems.
I did look at the calcium content, and it was only a difference of 3% instead of 1%.
The difference of 3% vs 1% can be enough to cause problems. Again, long term.
