Yesterday I put out some new wheat seeds and some 13-13-13 on my rye grass patches and along with the wheat seeds. I figured it was gonna rain today and dissolve the 13 13 13 before I let my birds range. Well it didn't rain. I was on the phone and while I was checking for eggs I turned my younger birds loose to free range! Totally forgot about the wheat and 13 13 13 after about ten min I realized it and ran then back into the coop. I'm hoping they at none to very little of the fertilizer. They had plenty of food, rye grass and wheat seeds to eat so I'm hoping they over looked the fertilizer! I gave them some bread in little pieces to help and they have fresh water! And suggestions? I tried to call my vet but he's in surgery and I'm waiting for a call back!
