they don't have impacted crops, they are piggy eaters. lol.
my NNs come from the same farm and probably are mixed with these chickens. Only my big fat NN and the black one lay jumbo size eggs, all the rest lay medium size tinted eggs. (one NN lays medium size pink eggs.)\
on the first pic you can see bella with a white leghorn, just to compare the size. the last pic is not good, but that is my wheatie. I desperately wanted a wheaten chicken and got it! bella, wheatie and meggie (red mottled) were bought as cockerels for meat (I wanted to try to raise chickens for meat but failed). luckily they turned out to be girls. and anita was supposed to be black NN and then the feathers grew up.
You say we have nice birds but I think you have nice birds!
It is a little hard to be very sure just from pictures.. The slow broiler hens I have are very big but pictures just don't show how BIG they really are....
The first two do have the 'broiler blood' look.. the wheaten one, she looks a little slender. I go back and forth on the black one being possible broiler mix.. she seems to have the long body common in broiler mixes but she doesn't seem very meaty?
The best way to tell is by picking them up and feeling the breast and legs, the breast should give the feeling of almost double the meat than a regular chicken and the legs should be very massive and hard on older bird. Compare it to the local chicken breeds- I remember you had a broody hen with a crest, right? She is "typical chicken".
Weight is a good clue, a hen weighing more than 7 lbs (3kg, is that correct?) is heavier than normal. So a hen weighing 9-10 lbs(4-4.5kg) definitely has broiler blood in it.
One last thing.. I don't know anything about European chickens.. are mottled chickens common? I ask this because white leghorns and white broiler stock usually have many genes thrown in to make them cleaner white, mottle is a common one. I wonder if the mottle on your birds could have come from the broiler stock... but if mottle is common on regular chickens, then that's not a very good hint.
by the way- egg size is genetic.. if you like the jumbo eggs and want more, hatch their eggs and save both daughters and sons for breeding. Big egg size is very easily lost so don;t be too surprised if the daughters lay regular or small.. this is why you want to save a son, he will have the big egg genes too. Either breed them with each other or back to the big egg hens.
My slow broiler hens laid small eggs as pullets... as they got older the eggs came up to a medium or just about large size. Not very big eggs at all.
