I have production red hens that the shell quality suffers when just being on all flock. I now mix roughly 1 scoop Poulin Grain Layer and 2 scoops allflock and am happier with the shell thickness.I found mixing the two is a great combination especially for winter...... Let me know what you guys think
I think especially with high production birds like Leghorns and Production reds you can not just give low calcium feeds such as flock raiser/starter/all flock type products. Yes I have Oyster shell in two separate containers also.
