Last week I went and bought a different brand of layer mash(it was on sale). Some of them also started laying eggs last week - woohoo! They just don't seem to eat as much of it as the previous brand I purchased...any ideas? I'm new to chickens, just want to make sure my girls are getting what they need. I normally give them 2 treats a day bread for a treat in the morning, sometimes peas or cooked carrots, lettuce or raisins at night. My husband will also throw in grass after mowing the lawn. Do you think I should be worried? They seem to act ok, they are NOT free range chickens.
