I have 7 - 25 week old chickens that have not yet showed signs of wanting to start laying (no squatting etc...) 2 of the 7 have very bright red combs and wattles but the others are still pale pink. In addition to the chickens in the picture I have 3 polish and I believe they are slow to mature. I only have about a weeks worth of finisher/grower pellets left for them. Should I buy the layer food or another bag of finisher/grower? I just don't want to buy another 20 lb bag of finisher/grower and have to buy the layer food in a few weeks. Thoughts????
