Your point is valid for show (or heritage) birds, but point of lay pullets are typically worth significantly more than are chicks. It was clear that the neighbor bought birds from a breeder, but not clear as to the type of birds (show, heritage, barnyard mix. Show birds ca be even more expensive than you mention. Cost for point of lay pullets is easily $25 in many areas.25 30$ a bird is a good price if its a show quality bird one of my silkies cost my 85$ for one bird! The other was 100$.But mine are show quality. do you know if her birds were show birds? If they were they likely costed a lot more than 35$. If they were hatchery birds then she likely got them for a whole lot less and
is over charging you. Do you know if they were show quality or hatchery? I'd find out and bring that up to her if she is over charging you. However if they were show quality your getting off cheap. Hope this helps. Best of luck
As for letting the birds free-range in their own yard and not clipping wings, that really has no bearing and should not have been mentioned at all. It is up to the neighbors, who owned the birds, to determine how they plan on raising them. MANY people choose to let their flocks free-range in their own yards. Now if the birds had gotten into the OP's yard, and the neighbors upset about the dogs getting them, those would be pertinent points, and the OP would not have done anything wrong. But the fact is that the dogs were the ones who were not where they were supposed to be. It doesn't matter whether the pullets were out unsupervised or not; that was the neighbor's choice.
