over the last 2 days , i've noticed that some of my birds are pooping soft piles of poo ..... not the typical logs so to speak ......... im feeding them layena pellets , and corn ....treats have included bread, eggs , oats, bacon grease(in my flock blocks) hot dogs , and one time i gave them cream cheese that was wrapped with chicken ....... should i be concered or is it normal for them to have poops like that when they eat certain foods ?
