Unbiblical Passover traditions

The seder plate with the ishtar egg and the broken bones of the sheep are NOT how we are to celebrate Passover.  When I lived in Seattle, my muslim landlords were able to find a whole sheep with unbroken bones when they roasted it for ramadan so it is not impossible to do (they found an adult sheep - Passover is to be observed with a smaller lamb less than a year old)    Also goats are acceptable for Passover (and that is worthy of a discussion)

How do people justify the lamb shank as a "representation" when Yahweh warns to observe according to HIS regulations?  How do people justify using the babylonian egg in a celebration of Yahweh? How do people justify the seder plate representation while fixing meat of some other animal for the real meal?  Yahweh is clear we are to eat the lamb - with unbroken bones - not use a [broken] shank bone to represent it and then eating chicken, turkey, or some other animal.  The roasted egg is directly from babylon and is from ishtar eggs that are used in ishtar (easter) celebrations.

Note those who are away from Jerusalem are to observe it in the SECOND month, not the first month.  How do people justify celebrating Passover in the first month when they are away from Israel? :

JPS

Numbers 9
10  'Speak unto the children of Israel, saying: If any man of you or of your generations shall be unclean by reason of a dead body, or be in a journey afar off, yet he shall keep the passover unto the LORD;
11  in the second month on the fourteenth day at dusk they shall keep it; they shall eat it with unleavened bread and bitter herbs;
12  they shall leave none of it unto the morning, nor break a bone thereof; according to all the statute of the passover they shall keep it.

CJB

Numbers 9
10  "Tell the people of Isra'el, 'If any of you now or in future generations is unclean because of a corpse, or if he is on a trip abroad, nevertheless he is to observe Pesach.
11  But he will observe it in the second month on the fourteenth day at dusk. They are to eat it with matzah and maror,
12  they are to leave none of it until morning, and they are not to break any of its bones — they are to observe it according to all the regulations of Pesach.

Verse 5 says the Passover lamb may be taken from the sheep or the goats and must be a male:

Exodus 12
1  And the LORD spoke unto Moses and Aaron in the land of Egypt, saying:
2  'This month shall be unto you the beginning of months; it shall be the first month of the year to you.
3  Speak ye unto all the congregation of Israel, saying: In the tenth day of this month they shall take to them every man a lamb, according to their fathers' houses, a lamb for a household;
4  and if the household be too little for a lamb, then shall he and his neighbour next unto his house take one according to the number of the souls; according to every man's eating ye shall make your count for the lamb.
5  Your lamb shall be without blemish, a male of the first year; ye shall take it from the sheep, or from the goats;
6  and ye shall keep it unto the fourteenth day of the same month; and the whole assembly of the congregation of Israel shall kill it at dusk.
7  And they shall take of the blood, and put it on the two side-posts and on the lintel, upon the houses wherein they shall eat it.
8  And they shall eat the flesh in that night, roast with fire, and unleavened bread; with bitter herbs they shall eat it.
