I would just like to add that I don't mean to be critical in any of the comments I have made, so please don't feel like I am putting you on the spot or trying to make you feel bad. None of us came into poultry keeping with all the knowledge we need.... it is learned by experience and reading and picking other people's brains. We all like to treat out chickens and chickens love treats, but there is a balance as with everything and it's easy to get too carried away with the treats and not realise the problems that can cause.... especially with the likes of scratch which is pretty much marketed as "chicken feed", so can be very confusing. The formulated feed (layer pellets/crumble etc) contains everything the chickens need to stay healthy and lay eggs. Once you give them anything else, they will eat less of the layer feed, which means that the balance gets thrown off. Top of the pecking order chickens often get first dibs at the treats, so may get more than their fair share, possible meaning that they are more prone to an imbalance and problems as a result. These are just things to be aware of and take into consideration when you start seeing problems.
